Margaret Harris, a British set designer who worked with two design collaborators in an award-winning, industrious firm called Motley, died May 10 in London at the age of 95, The New York Times reported.

Born in Shortlands, Kent, in 1904, Ms. Harris would partner with designers Audrey Sophia Harris (her sister) and Elizabeth Montgomery to form an outfit that created sets and costumes for London, regional, international opera and Broadway productions.

They were rare female theatrical designers in an arts world then dominated by men. Motley earned two costume design Tony Awards and five nominations in all over the years. Their Tony winning costumes were seen in Becket in 1961 and The First Gentleman in 1958.

Settings and costumes by Motley (a name taken from Shakespeare) were seen in more than 300 productions between 1932 and the 1970s.

Their early setting and costume designs included Oxford University Dramatic Society's Romeo and Juliet in 1932, Merchant of Venice at the Old Vic in 1932, and the ballet The Haunted Ballroom at Saddler's Wells. The firm was nominated for Tonys for costumes for Baker Street, Mother Courage and Her Children and Kwamina. -- By Kenneth Jones
