Sibyl Wilbur (1871-1946) was born in Elmira, New York, and died in San Diego, California. Her parents died when she was young, and by age 14 she had moved to Nebraska and was earning a living by teaching at a prairie school. She saved enough money to attend a Minneapolis, Minnesota, prep school before enrolling in Hamline University, a Methodist college in St. Paul, Minnesota. At 21 she began her journalistic career at the Minnesota Journal. Over the next two decades she wrote about women's rights, labor issues, and culture, working for major metropolitan newspapers in New York, Chicago, Washington, D.C., Minneapolis, and Boston. She was politically active as an organizer in the Woman Suffrage Party in New York City. In 1896, she married a journalist in Washington, D. C., named O'Brien, however the marriage eventually dissolved. Wilbur interviewed Mary Baker Eddy at Pleasant View, Eddy's home in Concord, New Hampshire, for the Boston Herald in May 1905. After doing so, she looked to defend Eddy against attacks by several newspapers, as well as McClure's Magazine, which had been publishing a series attempting to discredit Eddy. Wilbur sought to refute this effort by publishing a monthly series of articles in Human Life magazine between December 1906 and December 1907. The series became the basis for her book, The Life of Mary Baker Eddy (1908), which was the first published biography of Eddy. In 1907, Wilbur took a personal interest in Christian Science and had Primary class instruction with Alfred Farlow, one of Eddy's students, however we have found no further information concerning her continued involvement with Christian Science. She moved to San Diego in 1918, after marrying John S. Stone that year in New York, New York. Following their divorce in 1930, she remained in the city and was very involved with the women's suffrage movement there until her passing. Wilbur was a San Diego Branch Member of the National League of American Pen Women and a member of the New England Woman's Press Association.
