Reinhard studied design and composition in his native Germany before moving to the U.S. in 1961 at the age of 20 to continue his education at the Art Center School in Los Angeles. Over the following 15 years, Reinhard's work spanned dozens of animated TV commercials, to motion pictures, to over a hundred life-sized paper sculptures for television variety shows and specials hosted by such celebrities as: Bing Cosby, Bob Hope, Diana Ross, Bill Cosby and Carol Burnett.

In 1974 Reinhard dissolved his studio in Hollywood and transitioned into graphic design and illustration. He relocated to to the East Coast where he created a variety of illustrations for the advertising and publishing industry including: Max Factor, New York Times, Seagram, and Coca Cola, and has received Numerous awards from the Society of Illustrators.

He resumed his academic training at the Art Center School in Los Angeles and the School of Visual Arts in New York. In 1976, Reinhard published a series of fine art posters and prints, many of which have musical motifs in a delightfully humorous fantasy setting. His best known work, "The Rehearsal", a four-by-six foot sculpture of the Alban Berg String Quartet, earned him acclaim throughout the world. It has been shown in the Oakland Art Museum, Mint Museum in North Carolina, and the Historical Society Museum in New York City.

His work has been exhibited in over 200 galleries worldwide and is in public and private collections.
