The "Soldierking" Frederick William (King in #Prussia and Elector of #Brandenburg from 1713 to 1740) had problems with his knees and legs during his last months in 1740. Before he died (31 May 1740), someone close to him wrote this entry in February 1740 into a #Schreibkalender: „Deß Königs Lincke Bein sehr geschwollen gewesen“.
More about this and the potential of writing calendars as sources for many fields soon. @histodons#histodons
