Soon after the invasion in March 1945, the Americans opened the "Red Cross Eagle Club" for American officers in the confiscated Wiesbaden Kurhaus. Musical and cabaret performances took place in the Eagle Club, and there was a fitness room for lifting weights and boxing. There was a movie theater and other activities such as ping-pong and chess tournaments, French and German language courses, dance and piano lessons, bridge courses, boogie-woogie tournaments and much more. Many American stars and starlets, including the actresses and dancers Paulette Goddard, Lana Turner, Martha Raye, Zsa Zsa Gabor, Rita Hayworth, but also Frank Sinatra performed. Jazz and swing evenings, variety acts, performances by comedians, wrestling competitions and horse shows were offered. More serious entertainment included charity concerts with Walter Gieseking and performances of German folk songs by the Wiesbaden Men's Choir. Hazi Osterwald and his quartet also made guest appearances in Wiesbaden.

From March 1947, German women were allowed to attend special events. A further relief came two months later. Now all Germans accompanied by Americans could attend the Tuesday concerts at the Eagle Club. In September 1947, the American Red Cross handed over the organization of the club to the Special Service. After the signing of a contract for the joint use of the Kurhaus by the Germans, the Eagle Club moved to the Villa Söhnlein-Pabst, where the reopening was celebrated on October 25, 1954.
