He came to the U.S. from Austria during World War II, and apprenticed with a diamantaire. He later became a master diamond cutter before inventing the Radiant Cut in 1976. Henry Grossbard died in 2005 in a hit and run accident, while walking his dog on Passover. The killer was never found. His son, Stanley Grossbard, assumed responsibilities for RCDC Corp. following Grossbard's death. Stanley Grossbard is married to Hoboken Mayor Dawn Zimmer.
