Petar Beron
Petar Beron (Bulgarian: Петър Берон) (c. 1799, Kotel – 21 March 1871) was a Bulgarian educator, teacher, doctor, maecenas, and author.
He created the first modern Bulgarian primer, known as the Fish Primer (Рибен буквар, Riben bukvar) due to a dolphin drawn in the end of the book. Beron has been called "the father of modern Bulgaria."
