JOCELYN BELL BURNELL: THE FIRST RADIO PULSARS

Jocelyn Bell
Susan Jocelyn Bell Burnell (1943) is a Northern Irish astrophysicist. As a postgraduate student, she discovered the first radio pulsars while studying and advised by her thesis supervisor Antony Hewish, for which Hewish shared the Nobel Prize in Physics with astronomer Martin Ryle, while Bell Burnell was excluded, despite having been the first to observe and precisely analyse the pulsars. 

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 was interim president following the death of her successor, Marshall Stoneham, in early 2011. She was succeeded in October 2011 by Sir Peter Knight. Bell Burnell was elected as President of the Royal Society of Edinburgh in October 2014. In March 2013 she was elected Pro-Chancellor of the University of Dublin.

The paper announcing the discovery of pulsars had five authors. Hewish's name was listed first, Bell's second. Hewish was awarded the Nobel Prize, along with Martin Ryle, without the inclusion of Bell as a co-recipient. Many prominent astronomers criticised this omission, including Sir Fred Hoyle The Royal Swedish Academy of Sciences, in their press release announcing the 1974 Nobel Prize in Physics, cited Ryle and Hewish for their pioneering work in radio-astrophysics, with particular mention of Ryle's work on aperture-synthesis technique, and Hewish's decisive role in the discovery of pulsars.

The fact that Bell did not receive recognition in the 1974 Nobel Prize in Physics has been a point of controversy ever since. She helped build the four-acre radio telescope over two years and initially noticed the anomaly, sometimes reviewing as much as 96 feet of paper data per night. Bell later claimed that she had to be persistent in reporting the anomaly in the face of scepticism from Hewish, who was initially insistent that it was due to interference and man-made. She spoke of meetings held by Hewish and Ryle to which she was not invited.

because you never ever get there.
