Alexander Graham Bell (March 3, 1847 – August 2, 1922)

Thomas Alva Edison (February 11, 1847 – October 18, 1931)
Thomas Edison was born in 1847 in Milan, Ohio, but
grew up in Port Huron, Michigan.
Early in his career he worked as a telegraph operator,
which inspired some of his earliest inventions.
In 1876, he established his first laboratory facility in
Menlo Park, New Jersey.
Duct tape is born when Vesta Stoudt (1891 – 1966) a
factory worker packing WWII munitions, writes FDR
outlining—with drawings—her idea to replace weak
paper packing tape with a tougher waterproof cloth
version. Impressed, FDR pushed her idea into
production.

(September 15, 1846 – August 21, 1910)
On this day in 1899, George F. Grant, an African American
dentist from Boston, received US Patent number 638,920
for the world’s first golf tee.
Neither a marketer nor an inventor, Grant, who was also
the first African-American professor at Harvard, gave
away a few copies of his creation but made no money
from it before he died.

The question, taken from the Bible (Numbers 23:23), had been
suggested to Morse by Annie Ellworth, the daughter of the
commissioner of patents.
