Jocelyn Bell Burnell

Dame Susan Jocelyn Bell Burnell (; née Bell; born 15 July 1943) is a Northern Irish astrophysicist and radio astronomer who, while conducting research for her doctorate in 1967, discovered the first known pulsar. This discovery was recognized by the Nobel Prize in Physics in 1974, though she was not among its recipients. Bell Burnell was president of the Royal Astronomical Society from 2002 to 2004, president of the Institute of Physics from October 2008 until October 2010, and interim president of the Institute following the death of her successor, Marshall Stoneham, in early 2011. She was Chancellor of the University of Dundee from 2018 to 2023. In 2018, she was awarded the Special Breakthrough Prize in Fundamental Physics. Following the announcement of the award, she decided to use the $3 million (£2.3 million) prize money to establish a fund to help female, minority and refugee students to become research physicists. The fund is administered by the Institute of Physics. In 2021, Bell Burnell became the second female recipient (after Dorothy Hodgkin in 1976) of the Copley Medal. In 2025, Bell Burnell's image was included on an An Post stamp celebrating women in STEM.
