Petko Zadgorski is a Bulgarian artist and sculptor. He was born in 1902 in Sliven. Orphaned at an early age, he was raised and educated in the spirit of patriotic values ​​by his grandmother Ana - a relative of Hadji Dimitar. The line of affirming patriotism as a leading feature in the artist's work was continued in the years when Petko Zadgorski studied Painting in the class of Professor Dimitar Gyuzhenov at the Academy of Arts. It was in this period (1924-1928) that the young artist joined realistic art, plot composition, often associated with literary subtext. Soon after graduation, he started working as a drawing teacher in Burgas, where his students were the artists Georgi Baev and Todor Atanasov. When he arrived in the seaside town, Petko Zadgorski developed a passion for contemplating the tides and the sunsets sinking into the endless expanse of water. Zadgorski's love for the sea can be found in the impressionistic canvases "Fog Over the Raid", "Boats", "Landscape from the Salt Flats". The quest for union with the sea element takes him on long walks with the yacht he made himself. In fact, designing vessels is one of the artist's versatile interests.

In the 60s of the 20th century, the Society of Burgas Artists was established, with Petko Zadgorski as its first chairman. He is also the first restorer of the art gallery in the city, which today bears his name. In 1952 a bronze monument to Alexander Pushkin was discovered in the Sea Garden of Burgas - this monument, the work of Petko Zadgorski, is a symbol of the seaside city and is considered one of the best implementations of the theme worldwide. Zadgorski's oeuvre is not subject to classification according to the usual definitions of artistry - the richness of the genres is revealed by the easy transition from the landscape to the composition and the portrait, by the certainty with which the artist puts aside the brush to sculpt his exquisite sculptures.
