George W. Stewart
George W. Stewart, one of the country's foremost bandmasters and orchestra organizers, died at his home in Boston last Thursday after a year's illness. The body was brought to Cambridge, and burial took place in Woodlands Cemetery Sunday morning in the presence of a group of his old friends. The Rev. John Lloyd of Hoosick Falls officiated at the grave.
Born in Cambridge in 1851, the son of Dr. Joseph Stewart and Eliza Whitcomb Stewart, he took to music at an early age and played in the Cambridge Band, as well as with several circuses and minstrel shows. A talented barytone horn and trombone player, he became a member of the well-known Germania Band and the Boston Symphony orchestra. After ten years with the symphony, he organized his own Boston Festival Symphony Orchestra, which he led in concert at festivals throughout the eastern part of the United States and Canada. Always proud of his home town, he once brought his orchestra here for a concert which is still remembered.
Mr. Stewart's talents were so great that he was chosen to serve as music commissioner for two world's fairs, St. Louis in 1904 and San Francisco in 1915.
Surviving Mr. Stewart are a sister, Miss Rose Stewart, who gained fame as a concert singer and who traveled with the festival band as a concert soloist for many years; two nieces, Miss Rose Mosher of Boston and Mrs. Flora Stewart Craft of Glen Cove, L.I.; and four cousins, Miss Norma Whitcomb of Hoosick Falls, Ray Whitcomb of Lake George, Phillip Stoddard of Boston, and Warren Whitcomb of Cambridge (findagrave.com)
