Catherine Sarah Wood Marshall LeSourd was an American author of nonfiction, inspirational, and fiction works. She was the wife of well-known minister Peter Marshall. In 1940, Marshall contracted tuberculosis, for which at that time there was no antibiotic treatment. She spent nearly three years recovering from the illness. Her husband died in 1949 of a heart attack, leaving her to care for their 9-year-old son, Peter John Marshall. He later also became a minister and author. Marshall wrote a biography of her husband, A Man Called Peter, published in 1951. It became a nationwide success and was adapted as a film of the same name, released in 1955. Her success encouraged her to keep writing. Marshall wrote or edited more than 30 books, which have sold millions of copies. In 1959, Marshall married Leonard LeSourd, who was the editor of Guideposts Magazine for 28 years. Together they founded a book imprint, Chosen Books. They had three children, Linda, Chester and Jeffery. Marshall died on March 18, 1983 at the age of 68. Source: Wikipedia
