Rejto was born in Budapest. His first 'cello teacher was Frederick Teller, a local teacher whose ideas, for the time, were exceptionally forward looking. At sixteen, Rejto entered the Academy of Music under Adolf Schiffer (a pupil of and later assistant to David Popper), and two years later, with his Artist’s Diploma, he began his European concert career.
From the age of twenty, he studied with Pablo Casals for two years, first in Barcelona and then in Prades. Casals had revolutionized the approach to the 'cello and when he worked with Rejto, they spent almost a month on just basic technique. Rejto then played in concerts throughout Europe, with major symphony orchestras such as those in Vienna, Budapest, Rome and Warsaw, as well as in solo recitals.
Rejto was a resident of the United States from 1939 until his death. During his career, he was on the faculty of the Manhattan and Eastman Schools of Music. From 1954 to his death he was professor of 'cello at the University of Southern California. He was also one of the 'cellists in the Paganini Quartet and the Hungarian Quartet, and was a founding member of the Alma Trio, a piano trio, and remained with that ensemble from 1942 until it disbanded in 1976; in the early 1980s, the trio reformed, with Rejto again as the cellist. Mr. Rejto taught for a number of years at the Music Academy of the West summer program for gifted students, where his master classes were extremely popular, not just to cellists. His experience in chamber music attracted many students to his 'cello workshops held throughout the United States.
Rejto's son, Peter Rejto, is a cellist and a former faculty member at the Oberlin Conservatory. He was a founding member of the Los Angeles Piano Quartet. Gabor Rejto's daughter, Nika S. Rejto is a jazz flutist. She recently released a CD entitled "Teazing Socrates," which she dedicated to her late father.
