It is with great sorrow that we report on the passing of Professor Jacob D.=Bekenstein from the Hebrew University in Jerusalem, Israel. Jacob was born=in Mexico City in 1947 and obtained his undergraduate and M Sc degre=s in 1969 from the Polytechnic Institute of Brooklyn. His Ph.D work obtained. from Princeton University in 1972 und=r the guidance of John A. Wheeler contained his breakthrough discovery of =he Black hole entropy which started the subject of Black hole thermodynami=s. His findings were later further supported by the discovery of Black hole radiation by Hawking, who initial=y opposed the ideas of Bekenstein. He was a postdoctoral fellow at t=e University of Texas at Austin, and then faculty member (1974-1990)=at the Ben Gurion University in Israel where he became full professor in 1978 and then Arnow Professor of Astroph=sics in 1983. I had the fortune to be his post doctoral fellow at&nb=p; Ben Gurion University (1985-1988) at the time when he was develop=ng his famous Entropy Bounds, We worked on this subject and this was a great opportunity to get to know not only a great scientist=but also an outstanding human being. . Since 1990 he has been at the Hebre= University of Jerusalem (since 1993 as Polak Professor of Theoretical Phy=ics). Other scientific interests Jacob had have been relativistic magnetohydrodynamics, galactic dyna=ics, physical aspects of information theory, development of consiste=t theories with a time dependent fine structure constant, the development =f alternatives to dark matter by modifying gravity and more recently also designing realistic experiments to explore =uantum gravity. . Bekenstein was a member of the Israel Academy of Sciences and Humanities (since 1997) and of=The World Jewish Academy of Sciences., and has been honored with the =Landau Prize (1981), the Rothschild Prize (1988), the Israel National Prize (2005), the Weizmann Prize (2011), the Wolf Prize 2012 and most=nbsp; recently the Einstein Prize of the American Physical Society f=r 2015. He will be greatly missed as a great scientist and as = great man. He is survived by his wife Bilha and their three children.
