X-ray machines at shoe stores
The very first Nobel Prize for Physics was awarded to Röntgen for the discovery of X-rays. A year later his parents died and Röntgen inherited two million marks. He and his wife were now both rich and famous. He spent much time traveling, with little devotion to further scientific research. [http://ctct.essortment.com/wilhelmroentgen_rght.htm]

During the 1930s, 1940s and 1950s, many shoe stores used an X-ray machine to demonstrate how well a shoe fit the feet of the customer. By 1960 the practice had been discontinued in the United States because of safety concerns. The machines were still in use in Canada and Great Britain in the 1970s. <ref>http://www.orau.org/ptp/collection/shoefittingfluor/shoe.htm</ref>
