Florence Latimer Mars, 83, who defied the society into which she was born to write a searing book about the effects of the 1964 killings of the civil rights workers Andrew Goodman, Michael Schwerner and James Earl Chaney on her hometown, Philadelphia, Miss., died of congestive heart failure April 23 at her home there.
The author of Witness in Philadelphia, published in 1977 by Louisiana State University Press, she repeatedly spoke out against the Ku Klux Klan and other forces oppressing the black population of east-central Mississippi. A fourth-generation resident of the area and a member of its landed gentry, she was also a significant source of information for FBI agents investigating the killings, and she testified before a federal grand jury.
She paid for her efforts. The Klan organized a boycott against the stockyard where she sold cattle, forcing it to close, and she was compelled to resign from posts at the First United Methodist Church.
Julia Thorne, 61, the former wife of Sen. John Kerry who turned her experience with depression into a best-selling book, died of cancer Thursday in Concord, Mass.
Ms. Thorne, who struggled with depression for much of the 1980s, also founded a nonprofit education foundation called The Depression Initiative. In 1993, she wrote, with Larry Rothstein, You Are Not Alone: Words of Experience and Hope for the Journey Through Depression. A second book, A Change of Heart: Words of Experience and Hope for the Journey Through Divorce, was published in 1996.
She married Mr. Kerry in 1970. They divorced in 1988 but remained friendly, and she supported his 2004 presidential bid. She married Richard J. Charlesworth in 1997 and they lived in Bozeman, Mont.
Yuval Neeman, 80, founder of Israel's space program and a key figure in the nation's nuclear efforts, died after a stroke Wednesday at a Tel Aviv hospital.
Dr. Neeman, a world-renowned nuclear physicist, also played a role in Israeli politics. In 1979, he was one of the founders of the hawkish Tehiya Party, which broke away from the ruling Likud in opposition to Israel's peace treaty with Egypt. He served as science minister from 1990-1992.
He was a pioneer in Israel's nuclear program, serving as a member of the country's Nuclear Energy Commission between 1952 and 1961 and scientific director of one of Israel's nuclear reactors for two years. He established the Israel Space Agency in 1983, devoted to research and development of Israeli rockets and satellites. He died a day after Israel's latest satellite was launched into orbit on a Russian rocket.
William P. Gottlieb, 89, whose photographs of such jazz greats as Billie Holiday and Louis Armstrong are recognizable worldwide, died of a stroke April 23 at his home in Great Neck, N.Y.
His images have appeared in newspapers, museums, documentary films and on more than 250 album covers. His 1947 photo of a luminous Ms. Holiday -- eyes closed, head thrown back in song -- is said to be one of the most reproduced jazz photographs of all time.
