                               TO THE STOCKHOLDERS

     For the six  months  ended  June 30,  2003,  the  investment  return to our
stockholders was 15.2% (assuming  reinvestment of all dividends).  The net asset
value  per  Common  Share  increased  14%.  By  comparison,  the rate of  return
(including income) for our benchmark, the Standard & Poor's 500 Stock Index, was
11.8%. For the twelve months ended June 30, 2003, the return to our stockholders
was 0.5% and the return on the net asset value per Common Share was 1.7%;  these
compare with a return of 0.2% for the S&P 500. During each period,  the discount
at which our shares traded  fluctuated  moderately  and at June 30, 2003, it was
9%.

     As set forth in the accompanying  financial statements  (unaudited),  as of
June 30, 2003,  the net assets  applicable  to the  Company's  Common Stock were
$900,995,376, equal to $30.15 per Common Share.

     The increase in net assets  resulting  from  operations  for the six months
ended June 30, 2003 was $109,190,824.  During this period, the net realized loss
on securities sold was  $14,548,958 and the increase in unrealized  appreciation
was  $128,580,315.  Net  investment  income for the six months was  $559,467 and
distributions to preferred stockholders amounted to $5,400,000.

     During the six months,  679,300  shares of the Company's  Common Stock were
repurchased for $16,167,444 at an average discount from net asset value of 9.5%.

     Our portfolio  performed well during the period just ended,  reflecting the
outsized gains in a number of our core holdings.  The reduction and equalization
of the rate of taxation on capital  gains and  dividends  appears to have buoyed
investor confidence. The stock market may be anticipating an imminent step-up in
the rate of economic activity moreover,  resulting from the massive monetary and
fiscal  stimulus  in place  beforehand.  At current  valuations,  however,  some
measure of recovery  and  consequent  growth in earnings may be reflected in the
market.

     On July 9,  2003,  the Board of  Directors  authorized  the  redemption  on
September  23,  2003 of all of the  shares  of 7.20%  Tax-Advantaged  Cumulative
Preferred Stock then outstanding at the redemption price of $25.00 per share. In
addition,  the directors authorized the filing of a registration  statement with
the U.S.  Securities and Exchange Commission for the public offering and sale of
shares of a new series of preferred  stock.  The amount of capital to be raised,
the dividend rate and the timing of the offering have not been determined at the
present  time.

     The  information  about the Company,  including our  investment  objective,
operating  policies  and  procedures,  investment  results,  record of  dividend
payments,  financial  reports and press  releases,  contained at our website has
been  updated  through  June 30,  2003.  It can be accessed  on the  Internet at

9                  NOTES TO FINANCIAL STATEMENTS (Unaudited)
--------------------------------------------------------------------------------
                         General American Investors

                       1. SIGNIFICANT ACCOUNTING POLICIES

General American Investors Company,  Inc. (the "Company"),  established in 1927,
is  registered  under  the  Investment  Company  Act of  1940  as a  closed-end,
diversified  management  investment  company.  It is  internally  managed by its
officers under the direction of the Board of Directors.

The preparation of financial statements in conformity with accounting principles
generally  accepted in the United States  requires  management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

a. SECURITY VALUATION Securities traded on securities exchanges or on the NASDAQ
National  Market System are valued at the last reported  sales price on the last
business day of the period.  Listed and NASDAQ securities for which no sales are
reported on that day and other securities traded in the over-the-counter  market
are valued at the last bid price (asked price for open short  positions)  on the
valuation date.  Corporate  discount notes and U.S. Treasury bills are valued at
amortized cost, which approximates market value.  Special holdings are valued at
fair value in the opinion of the directors.  In determining  fair value,  in the
case of restricted shares,  consideration is given to cost,  operating and other
financial data and, where  applicable,  subsequent  private  offerings or market
price of the  issuer's  unrestricted  shares (to which a 30 percent  discount is
applied).

b.  SHORT  SALES The  Company  may make  short  sales of  securities  for either
speculative or hedging purposes. When the Company makes a short sale, it borrows
the securities  sold short from a broker;  in addition,  the Company places cash
with that broker and securities in a segregated account with the custodian, both
as collateral for the short  position.  The Company may be required to pay a fee
to borrow the securities and may also be obligated to pay any dividends declared
on the  borrowed  securities.  The Company  will  realize a gain if the security
price decreases and a loss if the security price  increases  between the date of
the  short  sale  and the  date on  which  the  Company  replaces  the  borrowed
securities.

c. FEDERAL INCOME TAXES The Company's  policy is to fulfill the  requirements of
the Internal  Revenue Code applicable to regulated  investment  companies and to
distribute substantially all taxable income to its stockholders. Accordingly, no
provision for Federal income taxes is required.

d.  OTHER  As  customary  in  the  investment   company   industry,   securities
transactions   are  recorded  as  of  the  trade  date.   Dividend   income  and
distributions to stockholders are recorded as of the ex-dividend dates. Interest
income,  adjusted for  amortization of discount and premium on  investments,  is
earned from  settlement  date and is  recognized on the accrual  basis.  Cost of
short-term investments represents amortized cost.

                   2. Capital Stock and Dividend Distributions

The  authorized  capital stock of the Company  consists of 50,000,000  shares of
Common Stock,  $1.00 par value, and 10,000,000 shares of Preferred Stock,  $1.00
par value, of which 29,882,056 shares and 6,000,000 shares,  respectively,  were
outstanding at June 30, 2003.

On June 19,  1998,  the Company  issued and sold  6,000,000  shares of its 7.20%
Tax-Advantaged  Cumulative Preferred Stock. The Preferred Shares are noncallable
for 5 years and have a liquidation preference of $25.00 per share plus an amount
equal to accumulated and unpaid dividends to the date of redemption.

The Company is required to allocate  distributions  from long-term capital gains
and other  types of income  proportionately  among  holders  of shares of Common
Stock and  Preferred  Stock.  To the  extent  that  dividends  on the  shares of
Preferred  Stock are not paid from long-term  capital  gains,  they will be paid
from ordinary income or net short-term  capital gains or will represent a return
of capital.

Under the Investment Company Act of 1940, the Company is required to maintain an
asset coverage of at least 200% for the Preferred  Stock. In addition,  pursuant
to the Rating Agency  Guidelines,  the Company is required to maintain a certain
discounted  asset  coverage for its  portfolio  that equals or exceeds the Basic
Maintenance  Amount  under  the  guidelines  established  by  Moody's  Investors
Service,  Inc. The Company has met these  requirements since the issuance of the
Preferred Stock.

The holders of Preferred  Stock have voting  rights  equivalent  to those of the
holders of Common Stock (one vote per share) and, generally,  vote together with
the holders of Common Stock as a single class.

At all times, holders of Preferred Stock will elect two members of the Company's
Board of Directors and the holders of Preferred  and Common  Stock,  voting as a
single class,  will elect the remaining  directors.  If the Company fails to pay
dividends  on  the  Preferred  Stock  in an  amount  equal  to two  full  years'
dividends,  the  holders  of  Preferred  Stock  will  have the  right to elect a
majority of the  directors.  In  addition,  the  Investment  Company Act of 1940
requires that approval of the holders of a majority of any outstanding Preferred
Shares, voting separately as a class, would be required to (a) adopt any plan of
reorganization  that would adversely affect the Preferred Stock and (b) take any
action  requiring a vote of security  holders,  including,  among other  things,
changes in the Company's subclassification as a closed-end investment company or
changes in its fundamental investment policies.

The Company  classifies its Preferred Stock pursuant to the requirements of EITF
D-98,  Classification  and Measurement of Redeemable  Securities,  which require
that  preferred  stock for which its  redemption  is  outside  of the  Company's
control should be presented outside of net assets in the statement of assets and
liabilities.

On July 9, 2003,  the Board of Directors  authorized the redemption on September
23, 2003 of all of the shares of 7.20% Tax-Advantaged Cumulative Preferred Stock
then outstanding at the redemption  price of $25.00 per share. In addition,  the
directors  authorized  the  filing  of a  registration  statement  with the U.S.
Securities and Exchange Commission for the public offering and sale of shares of
a new series of  preferred  stock.  The  amount of  capital  to be  raised,  the
dividend rate and the timing of the offering have not been determined as of July
9, 2003.

                     INDEPENDENT ACCOUNTANTS' REVIEW REPORT
--------------------------------------------------------------------------------

To the Board of Directors and Stockholders of
GENERAL AMERICAN INVESTORS COMPANY, INC.

     We have reviewed the  accompanying  statement of assets and  liabilities of
General  American   Investors  Company,   Inc.,   including  the  statements  of
investments  and  securities  sold short,  as of June 30, 2003,  and the related
statements of operations and changes in net assets and financial  highlights for
the six month  period  ended  June 30,  2003.  These  financial  statements  and
financial highlights are the responsibility of the Company's management.

     We conducted our review in accordance  with  standards  established  by the
American  Institute  of  Certified  Public  Accountants.  A  review  of  interim
financial  information consists principally of applying analytical procedures to
financial  data, and making  inquiries of persons  responsible for financial and
accounting  matters.  It is  substantially  less  in  scope  than  an  audit  in
accordance with generally accepted auditing standards, the objective of which is
the  expression  of an opinion  regarding the  financial  statements  taken as a
whole. Accordingly, we do not express such an opinion.

     Based on our review,  we are not aware of any material  modifications  that
should be made to the interim financial statements referred to above for them to
be in conformity with  accounting  principles  generally  accepted in the United
States.

     We have previously audited, in accordance with auditing standards generally
accepted in the United  States,  the  statement of changes in net assets for the
year ended December 31, 2002 and financial highlights for each of the five years
in the period then ended and in our report, dated January 14, 2003, we expressed
an unqualified opinion on such financial statements and financial highlights.

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
MANAGEMENT INVESTMENT COMPANIES.

                    General American Investors Company, Inc.

                      PROXY VOTING POLICIES AND PROCEDURES


     General  American  Investors  Company,  Inc.  (the  "Company")  is uniquely
structured as an internally managed closed-end  investment company. Our research
efforts,  including the receipt and analysis of proxy  material,  are focused on
the securities in the Company's  portfolio,  as well as  alternative  investment
opportunities.  We vote proxies relating to our portfolio securities in the best
long-term interests of the Company.

     Our investment  approach  stresses  fundamental  security  analysis,  which
includes  an  evaluation  of the  integrity,  as  well as the  effectiveness  of
management  personnel.  In proxy material,  we review  management  proposals and
management  recommendations relating to shareholder proposals in order to, among
other things, gain assurance that management's positions are consistent with its
integrity and the long-term  interests of the company. We generally find this to
be the case and, accordingly, give significant weight to the views of management
when we vote proxies.

     Proposals  that may have an  impact  on the  rights  or  privileges  of the
securities held by the Company would be reviewed very carefully. The explanation
for a negative impact could justify the proposal; however, if such justification
were not present, we would vote against a significant reduction in the rights or
privileges associated with any of our holdings.

Proposals   relating  to  corporate   governance   matters  are  reviewed  on  a
case-by-case  basis.  When they involve  changes in the state of  incorporation,
mergers or other restructuring,  we would, if necessary,  complete our review of
the rationale for the proposal by contacting company  representatives  and, with
few  exceptions,  vote  in  favor  of  management's  recommendations.  Proposals
relating to anti-takeover provisions, such as staggered boards, poison pills and
supermajorities could be more problematic.  They would be considered in light of
our  assessment  of the  capability of current  management,  the duration of the
proposal, the negative impact it might have on the attractiveness of the company
to future "investors," among other factors. We can envision  circumstances under
which we would vote against an anti-takeover provision.

     Generally,  we would vote with management on proposals  relating to changes
to the company's capital structure, including increases and decreases of capital
and  issuances  of  preferred  stock;  however,  we would  review  the facts and
circumstances associated with each proposal before finalizing our decision.

     Well-structured stock option plans and management compensation programs are
essential for companies to attract and retain high caliber management personnel.
We generally vote in favor of proposals relating to these issues; however, there
could be an occasion on which we viewed such a proposal as over  reaching on the
part of management or having the potential for excessive  dilution when we would
vote against the proposal.

     Corporations should act in a responsible manner toward their employees, the
communities in which they are located, the customers they serve and the world at
large.  We have  observed  that most  stockholder  proposals  relating to social
issues focus on a narrow issue and the corporate position set forth in the proxy
material  provides a well-considered  response  demonstrating an appropriate and
responsible  action or position.  Accordingly,  we generally support  management
recommendations  on these types of proposals;  however,  we would  consider each
proposal on a case-by-case basis.

     We take voting proxies of securities  held in our portfolio very seriously.
As indicated above, it is an integral part of the analytical  process at General
American  Investors.  Each  proposal and any  competing  interests  are reviewed
carefully on a case-by-case basis.  Generally, we support and vote in accordance
with the  recommendations of management;  however,  the overriding basis for the
votes we cast is the best long-term interests of the Company.

ITEM 9. CONTROLS AND PROCEDURES.

Conclusions of principal officers concerning controls and procedures

(a) As of July 23, 2003, an evaluation was performed  under the  supervision and
with the  participation of the officers of General American  Investors  Company,
Inc. (the  "Company"),  including the principal  executive  officer  ("PEO") and
principal  financial  officer  ("PFO"),  of the  effectiveness  of the Company's
disclosure  controls and  procedures.  Based on that  evaluation,  the Company's
officers,  including the PEO and PFO,  concluded  that, as of July 23, 2003, the
Company's  disclosure  controls and procedures were reasonably designed so as to
ensure that  material  information  relating to the Company is made known to the
PEO and PFO.

(b) There have been no significant changes in the Company's internal controls or
in other factors that could  significantly  affect these controls  subsequent to
the date of their evaluation and until the filing of this report,  including any
corrective  actions  with  regard  to  significant   deficiencies  and  material
weaknesses.
