Robert Henry Treman (March 31, 1858 – January 4, 1937) was an American banker and financier who served as a director and deputy governor of the Federal Reserve Bank of New York.

He would go on to become the bank's president in 1901, a role in which he would stay for more than 30 years before becoming the chairman of the board and heading up a merger with the Ithaca Trust Company.

He remained a member of the board for 46 years until his death and, at the time, held the longest continuous record as a trustee in the history of the university.

He led beautification efforts of natural features on campus, such as Cascadilla Gorge and Fall Creek, protecting them from privatization and development and keeping them open for public use.

Following this engagement, Manning would later become involved in projects with the university, completing two campus master plans with landscape architect Bryant Fleming in 1910 and 1930.

[11] In 1901, Treman and his brother began building their family estates in Ithaca's East Hill, a new and prestigious neighborhood on the edge of the Cornell campus.

[3][2] His modified Arts and Crafts style house on 640 Stewart Avenue had a view of Cayuga Lake and was designed by architect William Henry Miller.

During a picnic trip to Enfield Glen and Lucifer Falls in 1914, he became concerned about the maintenance of pedestrian paths near area gorges.

[10] In 1916, Treman once again hired Warren H. Manning to advise on a plan to restore the trails in the forty acres of land around Lucifer Falls.
