In 1945, freshly returned from the combat zones in Europe and Africa, Gallagher was appointed to head AP operations in Germany. He helped oversee the launching of AP's
German News Service, based in Frankfurt which was instrumental in helping the German media rebuild after the war. In 1946 Gallagher covered the Nazi war crime trials at
Nuremberg. He outscooped his rivals on the verdicts by dashing 100 yards to where his wife, Betty, waited with an open phoneline. He led the Nuremberg coverage for the AP along with
Pulitzer Prize winners
Dan DeLuce and
Louis P. Lochner. In 1954 he was appointed Assistant General Manager of the AP, a position he retained until
Frank J. Starzel retired as General Manager in 1962. The AP board of directors chose Gallagher to take over the post. One of the duties he fulfilled as General Manager was to write the dedication for each of the annuals the AP produced for the years 1964-78, as well as for other AP publications such as
The Instant It Happened, a collection of famous journalistic photographs. ==References==
