Keith passed away peacefully June 6, 2022 after a lifelong struggle with myotonic dystrophy.

A lifelong resident of Princeton, he was a graduate of the Pennington School in Pennington, NJ.

He enjoyed bicycling, astronomy and fishing. One of his favorite possessions was an antique fishing pole, a gift of renowned astrophysicist Lyman Spitzer who was a neighbor and watched Keith fish on Lake Carnegie as a child.

He is survived by his mother Evelyn B. Martin, who he cared for for many years. He is also survived by his sister Beth Ann Fierro (formally Beth A. Martin) and his three children.

He was predeceased by his father David F. Martin, his brother Christopher K. Martin, and his brother D. Brian Martin who all passed away from complications of the same genetic condition.

In lieu of flowers donations can be made in Keith's name to the Muscular Dystrophy Association.
