POPPER, SIEGFRIED

POPPER, SIEGFRIED (1848–1933), Austro-Hungarian rear admiral and naval engineer. From 1871 to 1904 he served as an engineer on battleships and was then appointed head of naval construction with the rank of rear admiral. Popper developed new methods of naval warfare and almost all the Austrian battleships of his time, as well as torpedo boats and fast destroyers, were constructed under his direction. After his retirement he served in the Technische Hochschule in Vienna but was dismissed through Nazi pressure in 1933.
