William Staub - inventor of treadmill dies at his home. He was 96.
His family said that he was still using a treadmill as recently as two months ago, Fox News reported.
The mechanical engineer built his treadmill in the late 1960s. It was made up of 40 steel rollers covered by an orange belt, with orange dials to determine the time and speed.
Health and fitness pioneer Dr. Kenneth Cooper said that the treadmill was almost exclusively used by doctors to perform stress tests until Staub came along.
Missouri State kinesiology professor Barbara Bushman said the Philadelphia-born Staub changed the way people exercised.
