Jonah Kumalae (1874 - 1940) was a Hawaiian politician, businessman and prolific ukulele maker. His main period of ukulele manufacture began in 1911. In 1915 he displayed his instruments at the Panama-Pacific International Exposition of 1915, where his ukulele design won a Gold Award. From then on this gold award was incorporated into his peghead logos. The original Kumalae ukuleles were made until the early 1930s but the Kumalae brand name was resurrected in 2012 by Welkin Sound with modern Kumalae ukuleles made in China and Japan.
