Julie Campbell
Julie Campbell was born on 1June 1908 in Flushing, New York, USA. She was the daugther of Julia deFres (Sample) and Archibald Campbell, an Army Officer. She travelled widely during her childhood and, at the age of eight, won her first short story contest while living in Hawaii.
On 30 march 1933, she married Charles Tatham Jr. The marriage worked together on many magazine stories and articles. She had her own literary agency in the 1940s when Western Publishing invited literary agents to find authors who could produce mystery and adventure books that would be marketed to children at an affordable price. Campbell proposed four series, two that would be written by herself and the others by two of her authors Hal Burton and John Henry Cutler. Both series were published under her maiden name, Julie Campbell. The Ginny Gordon series consisted of five books published between 1948 and 1956, while her contribution to the Trixie Belden series consisted of six books between 1948 and 1958.
At the same time, Campbell stepped in to take over the Cherry Ames and Vicki Barr series and wrote twelve books in total for these series over the same time period. It is believed that Campbell wrote Cherry Ames, Cruise Nurse in three weeks during the same period she was also writing the first Trixie Belden and Ginny Gordon books.
As widow, Julie Tatham was living in an apartment building called Hunting Towers in Alexandria, when she passed away on 7 July 1999 at the age of 91.
