Eastman Kodak, Rochester, N.Y., said John M. Pietruski will resign as chairman and chief executive of its Sterling Drug unit and executive vice president of Kodak on Sept. 1. Pietruski headed Sterling Drug when it was acquired earlier this year by Kodak for $5.1 billion, thwarting a hostile takeover bid by F. Hoffmann-La Roche. No reason for his resignation was given, and his successor has not been named.
