Heinrich Ries (April 30, 1871 – April 11, 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.[1]
His first wife, Millie Timmerman Ries, a botanist and scientific illustrator who collaborated with Elizabeth Britton and Anna Murray Vail, died in 1942. He remarried in 1948, but his second wife, Mrs. Adelyn Halsy Gregg Ries, died early in 1950. He had two sons with his first wife Millie, Professor Victor H. Reis of Ohio State University, and Professor Donald T. Ries of Illinois State Normal University.[2]
Ries was president of the Geological Society of America in 1929.[3][4]
