Heinrich Ries, Ph.D. (1871–1951) was an American economic geologist, born in Brooklyn, New York, and educated at Columbia University and at the University of Berlin. He was employed principally at Cornell University, initially as an instructor (1898–1902), as an assistant professor (1902–1905), as professor, and as head of the geological department (1915- ). Professor Ries made numerous reports on clay published by the United States Geological Survey, the New York State Geological Survey and the Canadian Geological Survey.
His first wife, Mrs. Millie Timmerman Ries, died in 1942. He remarried in 1948, but his second wife, Mrs. Adelyn Halsy Gregg Ries, died early in 1950. He had two sons, Professor Victor H. Ries of Ohio State University, and Professor Donald T. Ries of Illinois State Normal University.
