Walter Edmond Sear (27 April 1930 – 29 April 2010) was an American recording engineer, musician, instrument importer and designer, inventor, composer and film producer. He was considered a pioneer in the use of the synthesizer and an expert on vintage recording equipment. Sear ran the Sear Sound recording studio (in Hell's Kitchen ); known for its vast collection of vintage analog recording equipment and patronized by artists including Steely Dan, Sonic Youth, David Bowie, Wynton Marsalis, Paul McCartney and Patti Smith.
Born in New Orleans, Louisiana, Sear moved with his family to Jackson Heights, Queens at the age of one. Sear started his long and varied career as a classical tuba player. After 4 years at the Curtis Institute of Music, he was employed as principal tuba player for the Philadelphia Orchestra. He later worked as a freelancer in New York City, playing for 6 years with the Radio City Music Hall pit orchestra as well as The Symphony of the Air, The Goldman Band, Sound of Music and numerous commercial studios.
In the late 1950s, he became interested in tuba design and began importing European tubas made to his own specifications from the Czech company Cerveny and the Belgian companies De Prins and Mahillion. He sold these tubas from a Manhattan showroom. These tubas, popular because of their relatively low price, unique design and quality workmanship, were typically engraved with the name "Walter E. Sear, NYC" on the bell. Sear estimated that he imported/produced approximately 2000 such instruments. His background in chemistry (Temple University with BA degree from the George Washington University) helped with the metallurgical processes that he innovated. He also held a B.M. from the Catholic University of America and undertook doctoral studies at Columbia University.
