Retired from medicine, Dr. Peter Beron writes in every field of science, is a member of various international scientific societies, knows 9 languages. More than 20 schools, including girls only, were found with his material help - one of them is the girls' school in Kotel. In one of his letters to the Kotel old men wrote:
"I would like to find someone to pay, to go and see if there is a school in every town in Bulgaria..."
After the death of Peter Beron with the money from his inheritance, Edirne's male high school was found, which for 30 years sustains by the inheritance interest. The "Dr. P. Beron" Fund was also created, which provides scholarships to the children of Kotel who want to continue their education.

The bukvar (ABC book) is also the first Bulgarian children's book. For the first time there are artistic readings of a secular nature. For the first time, there are also health tips on how to keep a person healthy. For the reference, Yurii Venelin says, "I have not seen a single Russian letter to compare with the merits of this teaching book." The book underwent six editions in huge circulation during the period 1824 - 1862.
