Answer 2

No, the mechanical wheelchair was not available during Roosevelt's day. See following history:

Wheelchairs date back to the 16th century, when Jehan Lhermite built the first one for Philip II of Spain. In the 19th century, designers attempted to improve wheelchair design by using wicker instead of heavy wood in order to make them lighter. However, the wicker couldn't handle the stresses and strains of daily use, so chair designers went back to using wood. In 1919, Herbert Everest, a mining engineer, broke his back in a mining accident. Dissatisfied with his unwieldy wooden wheelchair, he invented the first lightweight, folding wheelchair with the help of his friend Harry Jennings, a mechanical engineer. Several decades later, Everest & Jennings was the first company to produce a commercially available electric wheelchair.

PS: The next significant innovation in wheelchair history was the development of the electric wheelchair, which became available in Australia during the 1970s.
