This lighting and furniture designer was born in Germany and emigrated to the US in 1925. In 1927, he opened a studio in New York to design and fabricate architectural lighting.

The Aeron ergonomic chair was designed by Bill Stumpf, FIDSA (1936-2006), of Stumpf, Weber + Associates; and Don Chadwick (b. 1936) of Chadwick & Associates, and was produced by Herman Miller, Inc. It departed from the traditional upholstery-over-cushioning design, and instead was made of a stretched, semi-transparent, flexible mesh called Pellicle. The Aeron chair was available in three sizes, had adjustable armrests, varied bases and could be customized by adjustments to fit a range of body sizes and weights, or with extensions like lumbar support or sacral support. Stumpf and Chadwick also designed the Equa 1 chair together in 1984, also made by Herman Miller, Inc. IDSA named the design a “Design of the Decade” in 2000
