Bill Staub, who brought to market the first home treadmill, died last week at age 96 . Although the first motorized treadmill was developed in the early 1950s, it took Straub's entrepreneurial bent to get treadmills into the mainstream. In the late 1960s, Straub's company, Aerobics, Inc., introduced the PaceMaster 600. Straub was inspired by Ken Cooper's bestseller Aerobics to start running, and developed the treadmill so that he and other runners wouldn't use bad weather as an excuse to skip workouts. In this 2006 article , Runner's World singled out Staub's home treadmill as one of the top running-gear innovations of the last 40 years.
