Frederick Harer (November 15, 1879 – April 27, 1949) was an American painter, sculptor and etcher, best known for his skill as a gilder and framemaker. He produced frames for many of the Pennsylvania Impressionist painters, including Edward Redfield and Daniel Garber. Today, having a Harer frame on a Pennsylvania Impressionist painting adds significantly to its value. Harer was born in Blossburg, Pennsylvania. The son of a successful cabinetmaker, Harer had worked for his father as a youth and inherited his tools upon his father's death. He died on April 27, 1949, in Uhlerstown, Pennsylvania.
