Mathematicians Of The Day

22nd January

On this day in 1839, John Herschel heard of Daguerre's work on photography from a casual remark in a letter written by Beaufort to Margaret his wife. Without knowing any details, Herschel was able to take photographs himself within a few days.

On this day in 2019 Google released a Landau doodle.
