William Bruce's Elmwood Observatory in Hamilton.
The observatory, that Mr. Bruce built for himself, ...was located on Hamilton mountain in the area now just a couple of blocks east of Upper James, bounded by the streets Brucedale and Queensdale Avenues. This property was later gifted to the City of Hamilton in 1936, by Mr. Bruce's daughter, as a memorial to him and is now appropriately known as Bruce Park.
