In honor of Pulaski Day, the Ride asked readers to name the 19th century Polish inventor who, by studying bird flight, is believed to have created an early version of an airplane -- a glider he could steer with his feet.

Reader Carl Rollberg was the first to answer Jan Wnek, a sculptor for churches and cemeteries. He is said to have made flights between 1866 and 1869 at religious festivals and carnivals. He died after a fall in 1869.
