Sharon Rich has written eight books and edited and written over sixty magazine articles about 1930s singing stars Jeanette MacDonald and Nelson Eddy. She was close friends for many years with Jeanette's older sister, actress Blossom Rock (aka Marie Blake). Along with interviewing hundreds of people, Rich had access to many collections of private letters, Eddy’s personal scrapbooks, diary entries, FBI files and MacDonald’s unpublished autobiography.
She is considered by many to be the leading authority on MacDonald and Eddy in the world. "Sweethearts" (2001) was a selection of the Entertainment Book Club. In 1994 she was a guest speaker at the American Film Institute in Washington, D.C.
In 1995 she was awarded a Dame of Merit by the Knights of Malta for her contribution to History and Literature.
