Know all by these presents, that, effective as of March 3, 2009, the undersigned hereby constitutes and appoints each

appropriate to obtain codes and passwords enabling the undersigned to make electronic filings with the SEC of reports

required by Section 16(a) of the Securities Exchange Act of 1934 or any rule or regulation of the SEC;



(2) execute for and on behalf of the undersigned, in the undersigned's capacity as an officer and/or Member of the

Board of Directors of Walgreen Co. (the "Company"), Forms 3, 4, and 5 in accordance with Section 16(a) of the

Securities Exchange Act of 1934 and the rules and regulations thereunder;



(3) do and perform any and all acts for and on behalf of the undersigned which may be necessary or desirable to

complete and execute any such Form 3, 4, or 5, complete and execute any amendment or amendments thereto, and file such

form with the SEC and any stock exchange or similar authority; and



(4) 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 such

The undersigned hereby grants to each such attorney-in-fact full power and authority to do and perform any and every
