Joshua Lockwood Logan III (October 5, 1908 – July 12, 1988) was an American theatre and film director, playwright and screenwriter, and actor.

[3] Moreover, he was involved with the intercollegiate summer stock company, known as the University Players, with fellow student James Stewart and also non-students Henry Fonda and Margaret Sullavan.

Before his graduation, he won a scholarship to travel to Moscow to observe the rehearsals of Konstantin Stanislavski, and Logan left school without a diploma.

Logan returned to Broadway where he had his first major success as a director with Paul Osborn's On Borrowed Time (1938), which ran for 321 performances.

Logan's golden run continued with Mister Roberts (1948–1951) which he co-wrote as well as directed; it ran for 1157 performances and earned him a Tony Award.

Logan shared the 1950 Pulitzer Prize for Drama with Richard Rodgers and Oscar Hammerstein II for co-writing South Pacific.

Although the mistakes were corrected, Logan wrote in his autobiography: "I knew then why people fight so hard to have their names in proper type.

My name had been so minimized that I lived through years of having people praise South Pacific in my presence without knowing I had had anything to do with it."

Logan wrote, produced and directed The Wisteria Tree (1950), an adaptation of The Cherry Orchard, which was a minor success.

When director John Ford became sick, Logan reluctantly returned to Hollywood to complete the filming of Mister Roberts (1955).

Logan returned to Broadway, directing Middle of the Night by Paddy Chayefsky, which ran 477 performances.

He visited Japan to direct Marlon Brando in Sayonara (1957), which earned him a second Oscar nomination for Best Director.

Logan returned to Hollywood with Tall Story (1960), which introduced Jane Fonda to movie audiences.

He appeared with his wife in the 1977 nightclub revue Musical Moments, featuring Logan's most popular Broadway numbers.

Logan experienced mood fluctuations for many years, which in the 1970s psychiatrist Ronald R. Fieve treated with lithium, and the two appeared on TV talk shows extolling its virtues.
