Stephen Hawking

The original Hawking "joins" BDS story from 2013:
According to the Guardian:

"Professor Stephen Hawking is backing the academic boycott of Israel by pulling out of a conference hosted by Israeli president Shimon Peres in Jerusalem as a protest at Israel's treatment of Palestinians.
Hawking, 71, the world-renowned theoretical physicist and former Lucasian Professor of Mathematics at the University of Cambridge, had accepted an invitation to headline the fifth annual president's conference, Facing Tomorrow, in June, which features major international personalities, attracts thousands of participants and this year will celebrate Peres's 90th birthday.
Hawking is in very poor health, but last week he wrote a brief letter to the Israeli president to say he had changed his mind. He has not announced his decision publicly, but a statement published by the British Committee for the Universities of Palestine with Hawking's approval described it as "his independent decision to respect the boycott, based upon his knowledge of Palestine, and on the unanimous advice of his own academic contacts there".
Hawking's decision marks another victory in the campaign for boycott, divestment and sanctions targeting Israeli academic institutions."-more
