The son of Hungarian immigrants, Ferdinand and Regina Neudorfer, Klein was a graduate of the Cooper Union for the Advancement of Science and Art and of New York University.
[1] Among his most well-known designs was the single family, six room house shown at the 1959 American National Exhibition in Moscow, where Richard Nixon and Soviet leader Nikita S. Khrushchev held their televised "Great Kitchen Debate."
[1][2] Larger Klein homes built in Jamaica, Queens, in New York City, and elsewhere featured a symmetrical colonial style; many of these larger brick homes still exist throughout Jamaica Estates and the rest of Queens.
[3][4] Klein also designed the Hillcrest Jewish Center, Temple Beth Sholom, and the Queensboro Jewish Center – all three of which are in Queens – in addition to the Pine Hollow Country Club, in East Norwich, New York.
[1] Klein died on April 12, 1992, at Long Island Jewish Hospital in New Hyde Park, New York.
