100th Guess the Chemist

100th Guess the Chemist

Author: ChemistryViews.org

ChemistryViews celebrates its tenth anniversary this year, and this month marks the 100th installment of our Guess the Chemist quiz. You can try to solve the latest quiz here.

Over the years, the quiz has covered many eminent chemists who have made important discoveries or useful inventions. You can read about the interesting life stories of these scientists by clicking on the links in the list below.

 

In addition to the quiz, this month there is a “Which chemist is in the picture?” competition on social media. We post a new picture every week on Instagram, Twitter, Facebook, and LinkedIn and uncover a little more of each picture every day. Participants have the chance to win a ChemistryViews power bank.
