Barbara Stanwyck and I began our relationship on Titanic, although we had actually met years before. For a time, my father had an eight-acre ranch in Chatsworth, across from the racetrack. Martha Scott also lived there, and I used to take care of her horse. We'd go riding, and I would see Barbara and her husband, Robert Taylor, riding. I would go trotting along with them, never thinking I'd be involved with her someday. Later, Barbara had a beautiful ranch at the corner of Devonshire and Reseda, with her agent, Zeppo Marx. It's now a shopping center, but when Barbara owned the ranch, it had paddocks that were impeccably maintained and run, like everything Barbara touched.
