Katherine Johnson 1918 - 2020

The Mathematical Association is sad to learn of the death of Katherine Johnson on February 24 at the age of 101. She was as American mathematician who played a pivotal part at NASA in the development of crewed space flight.

An article on her life was published in SYMmetryplus 68 last year and can be downloaded here.
