#OnThisDay, 24 Feb 1968, Jocelyn Bell Burnell - along with her male supervisor and three other men - published a paper confirming the discovery of pulsars. She had built the array, picked up the signal and argued it was not an anomaly. Hewish received the Nobel prize for it in 1974: Bell Burnell did not.
In 2018 Bell Burnell received a £3m prize for her work. She's used it to set up a foundation to improve the diversity in STEM.

While studying photographs taken in January, Clyde Tombaugh discovers Pluto, making it by far the first known object in the Kuiper belt. It was immediately hailed as the ninth planet.
However, its planetary status was questioned when it was found to be much smaller than expected. In 2006, the International Astronomical Union (IAU) formally redefined the term planet to exclude dwarf planets such as Pluto.

Leonardo da Vinci's Mona Lisa was stolen from the Louvre by museum employee Vincenzo Peruggia and was not recovered until two years later.

Geneticist Liane Russell was born #OTD in 1923.
She pioneered the study of mutagenesis and teratogenesis due to radiation, and identified the role of the Y chromosome in sex determination. Her work led to diagnostic x-ray safety standards for women of childbearing age.
Science, the joy of wild places, and civic engagement as a response to fascism – this is one of my favorite threads.
Antoni van Leeuwenhoek died #OTD in 1723.
A largely self-taught man in science, he is commonly known as "the Father of Microbiology", and one of the first microscopists and microbiologists.
