Sherman A. Groenke (11/15/1914 - 11/08/2008) was a combat artist with the Coast Guard in the South Pacific. Together with a writer and photographer, Groenke was commissioned to make a record of activities of the Coast Guard in various stations during WWII. During his free time he made sketches for a personal record, which he mailed home (probably in or near Milwaukee, Wisconsin). His paintings depict Gardner, Baker, and Canton Islands among others. I don't find mention of him on the TIGHAR website or in the old forum, anyone in the Milwaukee area care to pursue this?
