The Pruyn family of Albany, New York was one of the oldest and most esteemed Dutch families in New York, and at the time of Robert's birth, had resided in Albany for over two centuries.

In 1871, Pruyn went on to become president of the Embossing Company, one of the major toy manufacturers of the late nineteenth and early twentieth centuries. He was credited for five patents involving puzzles, dominoes, and building blocks. When John A. Dix became Governor of New York in 1873, Pruyn became an aide on the Governor's staff, and was later appointed a member of the New York State Board of Regents. Upon the appointment by President Grover Cleveland of National Commercial Bank of Albany President Daniel Manning as United States Secretary of the Treasury, Pruyn was named the bank's President. His secretaries included Charles E. Adams and Frederick Baldwin Adams. Pruyn and his staff became some of the more successful investors of the early twentieth century.

He held board memberships on eight major American companies and banks, and was also a member of various civic organizations. He also established the 13,000 acre (53 km²) Santanoni Preserve in the Adirondack Mountains upstate of New York, which is today a state park and National Historic Landmark.
