Radio engineer, amateur astronomer, and Chicagoan Grote Reber was born #OTD in 1911.
After reading about Karl Jansky’s accidental discovery of galactic radio emissions, he built a 9m radio telescope *in his back yard* and carried out the first radio survey of the sky. 🧪 ⚛️ 🔭 📡

When I was a little boy (i.e. early 1970's) my grandfather told me the story of how he, as a young apprentice, visited Germany in 1935 on a journey to upskill his agricultural crafts.

Computer science pioneer and United States Navy rear admiral Grace Hopper was born #OTD in 1906. 🧪 👩🔬
As far as I am aware, she is the only person who has both a supercomputer and a US Navy destroyer named after her. (1/n)
