Petroczy-Karman-Zurovec
PKZ 2
1918
The
Petroczy-Karman-Zurovec PKZ 2, despite its name, was
invented by Wilhelm Zurovec for which he alone
received German patent
No. 347,578, dated 12 February 1918. Unlike the PKZ-1,
which was government funded,
the PKZ 2 was privately financed by the
Hungarian Bank and the firm of Dr. Liptak & Co AG, a large iron
foundry and steel fabricator located near Budapest which established an
experimental section under Zurovec's
direction in late 1917.
The PKZ 2 has been amply described in post-war
and contemporary literature, yet in virtually all accounts the
design
is incorrectly attributed to Karman who, in 1919 by claiming sole
authorship and totally neglecting to
mention the true inventor, Wilhelm
Zurovec, deviously reaped the lion's share of the honors (documented
by
Zurovec correspondence in the Karman Archive). It is a great pity
that Zurovec has never received the full
measure of recognition that he
surely deserves as one of the outstanding pioneers.
