Rossiter was the son of Robert Raikes Raymond and Mary Ann Pratt, and husband of Sarah Mellen Dwight of Brooklyn, New York (married 1863).
A member of Henry Beecher’s Plymouth Church, Raymond held degrees from the Brookfield Polytechnic Institute (1857), Lafayette College (PhD 1868), Leigh University (LLD 1906), and the University of Pittsburgh (honorary LLD. 1915).

In 1945, the institute named its Rossiter W. Raymond Memorial Award after him, to recognize the best paper published by a member under 33 years of age.

He wrote at least one Western novel:
One of his best known quotes is:
Life is eternal; and love is immortal; and death is only a horizon; and a horizon is nothing save the limit of our sight.
