Know all by these presents, that the undersigned hereby constitutes and appoints

signing singly, his/her true and lawful attorney-in-fact, in regard to ownership
of securities for Unisys Corporation (the "Company"), to:

(1)  execute for and on behalf of the undersigned Forms 3, 4 and 5 in accordance
with Section 16(a) of the Securities Exchange Act of 1934 and the rules
thereunder;

(2)  do and perform any and all acts for and on behalf of the undersigned which
may be necessary or desirable to complete the execution of any such Form 3, 4
or 5 and the timely filing of such form with the United States Securities and
Exchange Commission and any other authority; and

(3)  take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be of benefit to,
in the best interest of, or legally required by, the undersigned, it being
understood that the documents executed by such attorney-in-fact on behalf of
the undersigned pursuant to this Power of Attorney shall be in such form and
shall contain such terms and conditions as such attorney-in-fact may approve
in his/her discretion.

The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform all and every act and thing whatsoever requisite,
necessary and proper to be done in the exercise of any of the rights and powers

such capacity at the request of the undersigned, are not assuming any of the
undersigned's responsibilities to comply with Section 16 of the Securities

Company, unless earlier revoked by the undersigned in a signed writing delivered
to the foregoing attorneys-in-fact.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
