Frederick Henry Baetjer was an American physician.

After graduating from medical school, Baetjer was a resident physician at Johns Hopkins Hospital, where the residents took turns "looking after the X-ray room". Baetjer's curiosity was piqued by the experience, and he began making nearly annual trips to Europe to visit X-ray facilities, including the laboratories of Heinrich Albers-Schönberg in Hamburg and Max Immelmann of Berlin.

Baetjer had one of his eyes surgically removed in 1908. Friends thought that Baetjer's eye problem might have been brought on by his X-ray work, but his physicians said that the cause was an accident he had in college.

By 1925, Baetjer had undergone 52 finger amputations over 16 years.
