George Keller was an American architect and engineer. He enjoyed a diverse and successful career, and was sought for his designs of bridges, houses, monuments, and various commercial and public buildings. Keller's most famous projects, however, are the Soldiers and Sailors Memorial Arch in Hartford, Connecticut, and the James A. Garfield Memorial in Cleveland, Ohio.

The James A. Garfield Memorial is a memorial for and the final resting place of assassinated President James A. Garfield, located in Lake View Cemetery in Cleveland, Ohio. The memorial, which began construction in October 1885 and was dedicated on May 30, 1890, exhibits a combination of Byzantine, Gothic, and Romanesque Revival architectural styles. Garfield, former First Lady Lucretia Garfield, and two other members of the Garfield family are entombed in the crypt level of the monument.
