John Greenwood

Managing Real Estate Broker with Fathom Realty PB00068179

John Greenwood was born in Boston, Massachusetts back in 1760.  He was best friends with Samuel Maverick a victim of the Boston Massacre. Things were not well at home, so at 16 he was sent to live with his uncle in Falmouth, Maine. 

When he learned about the Battle of Lexington and Concord in 1775 he left his uncles and walked alone for 150 miles stopping along the way at taverns to play music for the soldiers.  When asked where he was going, he replied “I’m going to fight for my country.”  He served under Captain Theodore Bliss’s company of the 26th Massachusetts regiment from 1775 to 1778.

He served as a fifer (a non-combatant military occupation). What you may not know about John is that he was also a dentist and inventor.  While you may not know John surely, you’ll recognize one of his patents George Washington.  Washington’s dentures were not made from wood but carved from a hippopotamus tusk.  He was also an inventor, he invented the first known “dental foot engine” in 1790.

I did know that George Washington's teeth were not made of wood but this was the first time I have heard the teeth were carved from hippopotamus tusks. Thank you for sharing this with me...

 Happy Sunday James Dray

Hello James - I readily admit that dental foot engine sent me on an online search because it was a unfamiliar term for me.  There were lots of rabbit holes I could have pursued but Barbara Todaro found an example that seems most "logical" to me.   And I agree, thankfully, dentistry has advanced much since the 18th century.

Interesting stuff and Barbara Todaro is quite the sidekick with the pictures that she shares.  I love reading about something then seeing a picture about it.

I'm sure glad dentistry has progressed from those days James Dray . Even with the current advancements I still hate going to the dentist.
