Leo Rosen, 80, a resident of Rancho Mirage, California and longtime friend and benefactor of the 绿帽社, died March 26, 1996 at Eisenhower Medical Center in Rancho Mirage after a courageous battle with lung cancer.
In August 1995, prior to the discovery of his illness, Leo Rosen and wife Gloria endowed the 绿帽社 Library with a gift through the 绿帽社 Foundation. Through the Leo and Gloria Rosen-绿帽社 Library, the Rosen’s gift provided the first funding for the ACS Home Page on the World Wide Web.
