Aleksey Nikolaevich Beloslyudov (16.03.1887-1939) - local historian, teacher.

Aleksey Nikolaevich Beloslyudov was born on March 16, 1887, in the city of Semey, in the family of a poor official of the Siberian Cossacks. After finishing the 7th grade of the Semey men's gymnasium, he was expelled for participating in illegal group activities in 1906. During this period, Aleksey Nikolaevich actively engaged in self-education and passed the exam for the primary school teacher profession in 1908.

Aleksey Nikolaevich dedicated his life to local history. Even while studying at the gymnasium, he frequently visited the Semey museum, helping to arrange exhibitions and organize the museum's materials. Later, he met the famous local historian Boris Gerasimov and learned the intricacies of local history work from him.

In 1906, together with his brothers, he opened a home museum in Semey, which later became known as the "Museum of the Beloslyudov Brothers." The Beloslyudov brothers collected their collection with great perseverance. Many archaeological finds were discovered near Semey: knives, pots, arrows, jewelry, and ancient coins. In terms of the significance of the artifacts, the museum of the Beloslyudov brothers was no less than the Semey city museum.

The museum had the following sections: geology and mineralogy, paleontology and anthropology, prehistoric archaeology, ancient items (books and manuscripts), numismatics, ethnography, and an art gallery. The numismatics section was particularly rich, containing over 1,000 coins, while the prehistoric archaeology section included more than 600 artifacts. The museum's collection totaled over 4,000 exhibits. The museum gained great popularity among the city's residents. At the first West Siberian exhibition, the museum of the Beloslyudov brothers was awarded a small silver medal.

The collection of material culture and ethnography monuments was closely related to expeditionary work. Aleksey Nikolaevich participated in various expeditions several times. In 1909, the brothers organized an ethnographic expedition to Lake Zaysan. In the summer of 1910-1911, he participated in archaeological expeditions in the regions of Oskemen and Zaysan. The expedition was led by V.I. Kamensky, the head of the Archaeology department of the Russian Academy of Sciences. The goal of the expedition was to map all archaeological monuments in this vast area on a two-verst map, excavate small burial mounds, obtain impressions of ancient inscriptions on monuments, and explore caves. The expedition included Chyetrkin and local archaeologist Beloslyudov.

A.N. Beloslyudov was also actively involved in collecting folklore. He recorded over 200 fairy tales, 97 riddles, and more than 100 songs. The collected materials were published in Siberian newspapers titled "Life of Altai" and "Siberian Life."
