Humphrey Bogart and Lauren Bacall: A Timeline of Their Hollywood Romance

Humphrey Bogart and Lauren Bacall were two of the most famous actors of their time, and their love story was one for the ages.

Despite the fact that Bogart was married when he met a 19-year-old Bacall in 1943, the two soon began a relationship that included meeting up secretly amid Bogart's divorce.

Between 1943 and 1948, Bacall and Bogart costarred in three movies together, including their first and most memorable, To Have and To Have Not. While Bacall almost lost her studio contract after the movie's director found out about their affair, the two persevered. They married on a friend's farm in Ohio in 1945.

Bogart and Bacall's son Stephen was born in 1949, and they welcomed their daughter Leslie in 1952. Bogart was diagnosed with cancer in 1956, and despite Bacall's support and care, he died in January 1957.

Bacall also admitted to being nervous around Bogart on set due to her inexperience.
