According to an article in the Boulder Daily Camera on 29 July [1941?], the Boulder weather station was located in the home of S. A. {note: this was Sidney A. or Sydney A., not G. A.} Giffin from 1 May 1897 to 30 July 1910, then Otto H. Wangelin kept the station in his home from 20 Aug. 1910 to 30 Apr. 1912. After Wangelin, the task of recording daily weather data went to Prof. J. A. Hunter, then to other professors at the University of Colorado, Boulder.
A Daily Camera in-house memo to news editor Bob Looney ( copy in BHS 351 b1 f09) notes that the Boulder weather station was moved from the Giffin home to that of O. H. Wangelin at 17th and Pine streets on 26 July 1910, following the death of S. A. Giffin, who had been the volunteer observer for many years. Wangelin was the editor of the Boulder County Herald.
