Mary Ellin Barrett, one of songwriter Irving Berlin’s three daughters and the author of a biography of her famous father, Irving Berlin: A Daughter’s Memoir, died July 16 in Manhattan. She was 95.

He often seemed a “shaky, uncertain man,” Ms. Barrett wrote of her father, yet out came hit after hit. In his lifetime, he wrote about 1,500 songs. A Russian immigrant, he wrote “God Bless America,” which has been thought of as an unofficial second national anthem; a Jewish man, he wrote “White Christmas,” one of the most beloved holiday songs.

In her lifetime, Ms. Barrett worked for Time magazine, also Glamour, Vogue and Cosmopolitan. In addition to the book about her father, she wrote three novels.
