Here is the revised version with improvements for grammar and clarity:

Kristin Hunter Lattany was a young adult writer whose work predominantly addresses race relations and the experience of growing up Black (and often poor) in America. Her books, translated into several languages and adapted into screenplays, provide a lens through which to visualize and analyze Black urban life after integration.

Born on September 12, 1931, in Philadelphia, Pennsylvania, Lattany grew up in a comfortable, middle-class neighborhood near Camden, New Jersey. As an only child, she was raised in an extended family, which included her father, George L. Eggleston, a military man and school principal, and her mother, Mabel Manigault-Eggleston, a pharmacist and teacher. Her upbringing also involved her grandmother and two aunts. Lattany discovered her two passions—reading and swimming—at an early age, and by age 4, she was reading adult books, which she smuggled from her parents' library.

Both of Lattany's parents encouraged her to become a teacher. She enrolled at the University of Pennsylvania in Philadelphia as an education major, completing her degree. However, her teaching career (in a third-grade classroom) lasted only four months. Realizing she wanted to be a writer, Lattany resigned from her teaching post, breaking her contract with the Camden school board.

In her early teens, Lattany began working as a columnist and feature writer for the Philadelphia edition of the Pittsburgh Courier, which connected her with other Black writers and journalists. As a young woman, she moved to Philadelphia and focused on achieving her writing goals.

In the 1950s and early 1960s, Lattany worked in various roles, including as an advertising copywriter for Lavenson Bureau of Advertising (1952–1959) and Werman & Schorr, Inc. (1962–1963) in Philadelphia. She also worked as a research assistant at the University of Pennsylvania (1961–1962) and as an information officer for the City of Philadelphia (1963–1966). In the 1970s, she returned to teaching on the college level, serving as a lecturer (1972–1979), adjunct associate professor of English (1981–1983), and senior lecturer (1983–1995) at the University of Pennsylvania's English Department. She also served as the director of the Walt Whitman Poetry Center in Camden, New Jersey (1978–1979), and as a writer-in-residence at Emory University in Atlanta in 1979.

Lattany's debut novel, God Bless the Child, was published in 1964. Her adult books include Landlord (which was adapted into a motion picture), Do Unto Others, Lakestown Rebellion, and Kinfolks. Her children's books include Boss Cat, Guests in the Promised Land (nominated for a National Book Award), and the bestselling Soul Brothers and Sister Lou.

Throughout her career, Lattany received numerous awards for her work as an author and artist for children and young adults. The Fund for the Republic awarded her first prize of $1,500 for a television script on school segregation titled A Minority of One, which was revised and aired on CBS's A Light Unto My Feet in 1956. In 1959, she received a John Hay Whitney Fellowship for minority group writing, and in 1965, she won the Athenaeum of Philadelphia Literary Award. Soul Brothers and Sister Lou earned the 1968 award from the Council on Interracial Books for Children for the best book by a Black author for ages 12 to 16, as well as the 1969 National Mass Media Brotherhood Gold Medal Award. In 1996, Lattany received the Black Writing Celebration Lifetime Achievement Award from Moonstone.

She married John L. Lattany on June 22, 1968, and became a stepmother to his two children, John Jr. and Andrew Lattany. Lattany passed away on November 14, 2008.
