Samuel K. Kamaka
(1890 - 1953)
2000 Hall of Fame Inductee
Samuel Kamaka is the founder of what is now Kamaka Hawaii, Inc., the leading manufacturer of quality ukuleles in the world. Kamaka began making ukuleles in his basement workshop in 1916. During the ukulele craze of the 1920s, a large number of manufacturers in Hawaii and on the mainland were making ukuleles. Kamaka's quality hand-crafted instruments and the introduction of his patented pineapple-shaped ukulele design gave him a solid piece of the competitive market, and by the late 1930s he was the only Hawaiian ukulele maker remaining in business. Kamaka Hawaii, Inc., continues to flourish under the direction of his sons and grandsons.
