Pannonica de Koenigswarter

was a British-born jazz patroness and writer. She was a leading patron of bebop music. She was a scion of the prominent Rothschild international financial dynasty.

Her friend Thelonious Monk reported that she was named after a species of butterfly her father had discovered, although her great-niece has found that the source of the name is a rare kind of moth.

The name “Pannonica” (nicknamed “Nica”) derives from Eastern Europe’s Pannonian plain.
