Early Life and Engineering Career

Wilhelm Kress was an Austrian engineer born in 1836, who played a significant role in the early development of aviation. In 1873, he relocated to Vienna, where he dedicated his work to the pursuit of human flight.

Pioneering Hang Glider Inventor

In 1877, Kress made a groundbreaking advancement by designing and building the first modern hang glider. This manually controlled gliding device represented a major leap forward in an era when engineers were still grappling with the challenges of creating heavier-than-air flying machines.

Efforts Towards Motorized Flight

At the turn of the 20th century, Kress joined the ranks of engineers determined to construct large-scale, motorized heavier-than-air aircraft. In 1900, he devised an innovative lever control system, though he failed to patent his invention (later claimed by French aviator Robert Esnault-Pelterie in 1907).

First Successful Water Launch Flight

Kress designed an aircraft intended for water takeoffs. In 1901, he successfully launched his aircraft from the waters of Lake Wienerwaldsee near Vienna. Although uncontrolled, this flight marked a milestone as it achieved a series of extended "hops" before crashing.

Challenges and Setbacks

Despite the initial success, Kress encountered setbacks. His aircraft was powered by a Daimler engine that was twice as heavy as planned, restricting it to half its intended power output. During an attempted takeoff, the aircraft's design proved inadequate, resulting in its destruction and an unsuccessful flight attempt.
