From throughout the ages.
Alexander Graham-Bell
Call me Maybe?
Nationality: Canadian/Scottish
Field: Engineering
Contributions: The telephone, but also tons of inventions from later in his life
Beard: The classic big bushy white beard like a Father Christmas with inventions instead of presents.
Gilbert Lewis
I'll be your electron-pair acceptor, baby
Nationality: U.S.A
Field: Chemistry
Contributions: Discovered covalent bonds and electron pairs, also contributed to the fields of thermodynamics and photochemistry.
Beard: Neat and stylish, but a good length. Slightly too respectable though, which may explain why despite getting 35 nominations, he never won a Nobel Prize
Norbert Rillieux
Sweet beard
Nationality: Creole American
Field: Engineering
Contributions: Developed a modern way of refining sugar that made it cheaper, easier and safer. Also developed a method for combating the Yellow Fever outbreak in New Orleans that was rejected by the state, only to be copied by white engineers a few years later.
Beard: Wiry goatee with bushy moustache combo. Most excellent.
Leonardo Da Vinci
"Great man, great beard"
Nationality: Italian
Field: Everything
Contributions: Leonardo invented so much stuff most of it was re-invented by other people because no one ever really got round to going through all his notebooks to work out what he wrote down. His contributions to the field of anatomy were extensive and legendary, and he also was a vegetarian who would buy and then free caged birds, which is awesome.
Beard Da Vinci has been so influential in everything he did I'm pretty sure most subsequent scientists have a beard is because of Leo.
