It's a sad day on Broadway. Arthur Laurents, the playwright behind the iconic musicals 'West Side Story' and 'Gyspy,' has passed away.

According to the New York Times, Laurent died Thursday from pneumonia complications at his Manhattan home. He was 93.

Though his work can be found across many genres, Laurents spent the majority of his career -- 65 years -- writing and directing plays, and did so up until just two years ago.

After several less successful endeavors, his big break came in 1957 with 'West Side Story,' his new spin on the classic 'Romeo and Juliet' story. Laurents took his play to composer Leonard Bernstein and lyricist Stephen Sondheim and together they created the unforgettable Broadway hit.
