Area of FocusAbout Ralf's Work
Ralf Hotchkiss is a rehabilitation engineer and a proponent of independent living for disabled people.
Hotchkiss designs wheelchairs and has set up a growing network of factories in twenty-five developing countries, where people with disabilities build state-of-the-art wheelchairs using inexpensive, local materials. His inventions include the Appropriate Technology International-Hotchkiss wheelchair, the “Torbellino Whirlwind.” He is the author of Independence Through Mobility (1985), a work that explains how to make wheelchairs simply and economically. He is currently experimenting with designs for all-terrain, off-road vehicles that will still function as effective wheelchairs in the kitchen, the work site, and the outhouse. His personal goal is to cross Africa by back roads with a vehicle that can be rebuilt by any blacksmith.
