Miss M. Sole succeeded Mr S. Juby* as assistant at the Albany Museum in 1901, under the directorship of Dr S. Sch?nland*. She collected many specimens for the museum that year and Sch?nland expressed great satisfaction with her work in his annual report. During 1902 Miss Sole and Miss M.F. Daly* collected many small insects. The next year she presented a collection of molluscs to the museum. She had left her post by 1905.
In his annual report for 1903 Sch?nland also acknowledged a donation of many molluscs received from Miss D. Sole and Miss G. Sole. These two ladies were presumably family members of Miss M. Sole. She may have been Minnie Amy Grace Sole, who was married to John M. Bowyer and died in 1947.
