  Bolander Banjo Uke
C.1900s, San Francisco CA

In 1917, a Hawaiian maker, Alvin D. Keech introduced his "banjulele-banjo", which became known as the banjolele or banjo ukulele. Although Keech (who later moved to England) claimed to have invented the instrument, and who trademarked the name 'banjulele', there were earlier pioneers working on the same design. John A, Bolander of California filed a patent for a banjo ukulele design with a closed back resonator on June 25, 1917. He had been manufacturing his "Bolander's Ukulele Banjo" at least since 1916
