Jacqueline Grennan Wexler

Jacqueline Grennan Wexler (born Jean Marie Grennan; August 2, 1926 – January 19, 2012), commonly known as Sister J, was an American Catholic former religious sister who rose to prominence when she, as President of Webster College, strove to convince the Holy See allow the transferral of the college's ownership to a lay board of trustees. Webster College became the first Catholic university to legally split from the Catholic Church. She later left her religious order, the Sisters of Loretto, and was President of Hunter College in New York City from 1970 to 1980. She went on to serve as President of the National Conference of Christians and Jews from 1982 to 1990.

Born in 1926 in Illinois, Wexler grew up on a farm and matriculated at Webster College in 1944. In 1948, she joined the Sisters of Loretto and went on to teach in Texas and Missouri. In 1957, she graduated with a master's degree from the University of Notre Dame, and in 1959, was transferred to work at Webster College, becoming Vice President in 1960. In 1965, Wexler succeeded Sister Francetta Barberis as president of the college. Wexler soon began major reforms, improving curricula, renovating and expanding the campus, and initiating volunteer service programs. In 1967, Grennan completed Webster College's transition to lay ownership, and she herself left her religious order.

In 1969, Wexler became President of Hunter College in Manhattan, part of the City University of New York. There, she dealt with student protests and expanded the college's healthcare curriculum and facilities. She left Hunter College in 1979, and in 1982, she became President of the National Conference of Christians and Jews, remaining until 1990, when she retired. She died in 2012 in Orlando, Florida.
