Hank Armstrong

Henry Jackson Jr (1912-1988) was an American professional boxer who fought under the name Hank Armstrong. He fought in the Featherweight, Welterweight, and Lightweight divisions. He is one of very few boxers who has held the championships of three weight divisions (Featherweight, 10/29/1937-9/12/1938; Welterweight, 5/31/1938-10/4/1940; Lightweight, 8/17/1938-8/22/1939). He is also the only boxer to hold three different weight classes' championships at the same time.

Hank Armstrong in The War That Came Early
Pete McGill reflected that the United States Navy's attempts to offer battle to its Japanese counterpart did not resemble the epic bout between Joe Louis and Max Schmeling, but was more like Hank Armstrong on benzedrine. (The Navy's commanders had expected a massive engagement resembling the Battle of Jutland, but were forced into retreat by enemy aircraft without even making contact with the main Japanese naval formation.)
