Isaac Adler

Isaac Adler (c. 1849–1918) was a German-American physician known for his published descriptions of lung cancer cases in the early 20th century.

Early life Isaac Adler was born in Alzey, Grand Duchy of Hesse, in about 1849 to Henriette Frankfurter and noted rabbi Samuel Adler. In 1857, the family emigrated to the United States. Adler received an undergraduate degree from Columbia College in 1868, then his M.D. in Heidelberg, Germany, in 1871. Adler noted "a decided increase" in lung cancer, and speculated that tobacco or alcohol could be involved. Adler suggested that lung cancer was frequently misdiagnosed as tuberculosis.

Personal life Adler married Frida Grumbacher on May 24, 1874. Adler died at his New York City home on May 4, 1918.
