Kenneth MacKenna (born Leo Mielziner Jr.; August 19, 1899 – January 15, 1962) was an American actor and film director.

On reaching manhood, he felt that it was his duty to take care of his entire family: mother, father and sibling.

His own professional success as a story director with MGM allowed him to help support his brother's career, give generously to others, and contribute to the theatre, even after his own death.

[citation needed] MacKenna and his wife, Mary Philips, both actors, were also long-time supporters of the arts.

This scarf was later given as a gift to Lucille Hackett (née Bardorf), cousin and beloved "sister" to Philips.

[citation needed] MacKenna died on January 15, 1962, in Santa Monica, California, at age 62.

[citation needed] Dore Schary, head of production at MGM in the 1950s, called MacKenna "intelligent and well educated — had good humor — and was incorruptible.
