Helene Kottanner

Helene Kottanner (née Wolfram; or ''Kottanner Jánosné''; c. 1400 – after 1470) was a Hungarian courtier and writer. Her last name is spelled variously as Kottanner, Kottanerin, or Kottannerin. She is primarily known to history as the author of memoirs about the years 1439 and 1440, when king Albert II of Germany died and his son Ladislaus the Posthumous was born. Kottanner, who dictated her life story in German, was a kammerfrau to Queen Elizabeth of Luxembourg (1409–1442). She also assisted Queen Elisabeth in a royal succession plot. Provided by Wikipedia
