Do you know what the medal for science, art and music looks like? I found nothing on google.
I found Glæsel by a lot of luck and a little bit hard work.
I made the assumption that the Wendish crown and Greek order was the most unusual and then searched through state calendars and writing down the possible matches and continued like this until there was only one possible candidate left.
Without searchable state calendars I would never have found him, at least not so fast.
Another of my (to many) projects is to make a excel file of all Swedes that received a Dannebrog orden.
