__How I Chose This Topic:__ I first saw the incident of Moisseiff's "Narrows bridge" collapse in 1940 on a television program. The Narrator explained how the bridge collapsed and his theory of "aerolastic flutter," stating that the longer the bridge, the more flexible it is. I was intrigued by this and later on researched more of Moisseiff's life. I found out that he lived in Riga, Latvia, immigrated to the U.S. when he was 19, and graduated from Columbia University with a degree in civil engineering. His collapse of Narrows bridge was one of the biggest mesups of his life and he quickly lost popularity. And although he helped make other famous bridges like the Manhattan and the Golden Gate, the collapse of "Galloping Gerdie" overshadowed tham all. Leon Moisseiff died of a heart attack in 1943.
