Alexander Hammid, born Alexandr Hackenschmied (Prague, 1907 – New York, 2004), was an influential Czechoslovak-born American director, cinematographer, and photographer. A key figure of the Czechoslovak film avant-garde in the 1930s, he became a central figure in American experimental cinema after immigrating to the United States. His collaboration with his then-wife Maya Deren was pivotal, culminating in their co-direction of the short film *Meshes of the Afternoon* (1943), a masterpiece of avant-garde cinema that explored the subconscious and non-linear narrative. His later career focused primarily on documentary and industrial films. His notable works also include *The Private Life of a Cat* (1947) and *To Be Alive!* (1964), co-directed with Francis Thompson, for which he won the Academy Award for Best Documentary Short Subject in 1965. Hammid was also a pioneer in the use of innovative film formats, such as IMAX, making a significant contribution to the evolution of visual language.
