Josef Franz Wagner (1856-1908) was a military bandmaster and composer known as the “Austrian March King.” He wrote “Under the Double Eagle,” his most popular and enduring composition, in 1902 It later became the official march of the 1st Austrian Artillery Regiment Number 2. The title refers to the double eagle in the coat of arms of the Austro-Hungarian double monarchy. America’s own “March King,” John Philip Sousa, liked the piece enough to record it three times with his own band.
