to list of innovators
E. Watson (1896-1983)
Born: Kansas City, MO (?)
A fascination with mechanical inventions led Watson to tinker
and work with machinery his entire life. After leaving the Army
in 1918, he worked as a machinist, layout man, and foreman, eventually
opening Western Machine Co., his own machine shop and contract
manufacturing business in 1946.
to his most successful invention-the telescoping shopping cart-,
Watson applied for and was granted four patents for mechanical
valves, pumps, and gauges, none of which were ever licensed or
telescoping shopping cart that Watson designed required no assembly,
and could be compactly stored by pushing one cart into another,
much like the carts of today. He manufactured several examples
in his Western Machine Co., and they debuted in 1947.
applied for a patent on his shopping cart in 1946, but it wasn't
until 1949 when Sylvan Goldman, the inventor of the first shopping
cart (patented in 1940), stopped contesting it and granted his
rights to the patent to Watson in exchange for licensing rights.
