EXPIRED: 09/18/09 – John Wild, 95, was 14 when he developed a bathtub-filling valve which automatically distributed hot & cold water just right. He later invented imaging techniques that became standard for ultrasound tumor screening & breast cancer diagnosis.
In retirement Wild spent several years restoring his 1928 Alvis car and the 1921 Harley Davidson motorcycle adapted to run on charcoal.
How will he be remembered? In 1994, the UK’s Royal Mail service issued a set of postage stamps to commemorate Wild’s pioneering work while Washington DC’s Smithsonian Institute has Wild’s early models of ultrasound equipment on exhibit. And on his 95th birthday this past August he received a letter of thanks for his life’s work from President Obama.
