Lloyd Gould Del Castillo was born in Boston in 1892 and his career as a child musician started very early. In 1914 he graduated Cum Laude from Harvard where he started the Harvard Musical Review as well as conducted Harvard's orchestra.  His career as theatre organist began at Boston's Fenway Theatre in 1917.  He went on to hold positions at many more prestigious theatres in the east as well as opened and operated his own theatre organ school before the invention of the 'talkies' in the early 1930's forced a stop to the whole operation.  After shutting down his organ playing school, his illustrious career as radio personality, organist, and arranger began.  Highlights of his career include the conducting of his own works of the Boston Pops Orchestra as well as his widely acclaimed (and humorous) column written for the ATOS under the pseudoname Dinny Timmins. He ended his career as pedagogue at the Sherman School of Music in Hollywood.  To his credit is also his book, Primer of Organ Stops that he dedicated to the ATOS (of which he was an active member throughout his life).  He died in 1992 at the age of 99 in Los Angeles.
