Alan B. Slifka

Alan Bruce Slifka (October 13, 1929 – February 4, 2011) was a New York investor and philanthropist, a co-founder of the Abraham Fund, and founding chairman of the Big Apple Circus.

[11] Together with sociologist Eugene Wiener, Slifka was a co-founder in 1989 of The Abraham Fund Initiatives, named for the common ancestor of Arabs and Jews, and served as chairman of the organization since its founding.

[8] The Abraham Fund works to advance a shared society of inclusion and equality between Jews and Arabs in Israel.

In addition to fostering Jewish values and education, the foundation also promotes biomedical research on sarcomas and autism spectrum disorders.

[14][4] Alan and his twin sister Barbara took control of 24-story office building 477 Madison Avenue in Manhattan after their father, Joseph Slifka, left it to them following his 1992 death.

[18][19][20] After Alan's death, his son Randy Slifka sued in March 2023 seeking $37 million in connection with the sale; that case was also dismissed.

[21][17] A Paul Weiss spokesman, speaking of the more recent suit, said "Mr. Slifka is a serial litigator who filed a nearly identical claim that was summarily dismissed last month in the same court.
