Charles W. Garside and his brother, George Garside, came to Juneau in 1884. They were mining engineers and early surveyors of the Juneau Townsite. George Garside was one of the original developers of the Perseverance, Atla and Jumbo lodes in the Silver Bow Basin (Stone 1980; DeArmond 1967).

The 1894 plat map of the Juneau Townsite shows Charles owning Lots 3 and 4 at the turn of the century. City tax records show that Charles Garside sold the two lots to William Bosch in 1912. The William Bosch House is part of the Telephone Hill Historic Neighborhood.
