His identical twin, Ronald, also began playing very young, and the two soon matched each other in ability.
Their parents paid for piano lessons, and they came under the wing of Eleanor Sokoloff, a teacher at the Curtis Institute of Music, and then were mentored by Pierre Luboshutz and Genia Nemenoff.
Some of the Marlowe Brothers' performances included music of Brahms, Mozart and Poulenc as well as some of their own renditions of Beatles’ melodies.
After college, the Marlowe brothers continued to tour, revising and perfecting their gig as identical twin music prodigies.
In later years both Ronald and Jeffrey Marlowe gave piano lessons to young performers in Maine and Pennsylvania respectively.
