Biography:

He was born on March 26 (according to the Julian calendar or 6 (according to other data on April 7) according to the Gregorian calendar) in 1868 in Kharkiv City of Kharkiv province of the Russian Empire in the merchant's family.

According to some data, only in 1912 he defended at the Imperial Kharkiv University a master's (candidate's) thesis "Determination of parallax of fixed stars by observations of the meridian circle of the Kharkov Astronomical Observatory". In his dissertation, the scientist identified the parallaxis of 59 stars, most of which have a large motion of their own. Boop's work has been awarded by the Russian Astronomical Society.

In 1894 he received the title of private associate professor of the Imperial Kharkiv University.

Since 1905 he began teaching activities at the Department of Astronomy at Imperial Kharkiv University. He lectured on astronomy (according to some data, only in 1914-1915), probability theory and geodesy (as certain archival data indicate, he studied these two subjects in 1903–1911).

Since 1906 he was a member of the Trial Committee at the Office of the Curator of the Kharkiv Educational District.

He participated in the general meetings of the International Astronomical Society in Vienna city in 1908 and Hamburg city in 1913.

During 1909-1915, observations were made on the meridian circle of the slopes and direct ascents of 1407 stars near the poles. The work was performed by Struve L. A., Evdokimov N. N. and Kudrevich B. I.

He took part in the expedition to observe the total solar eclipse in Genichesk city on the Azov Sea on August 21, 1914.

During 1915-1930 he headed the Observatory and Department of Astronomy at Kharkiv University.

During 1921-1933 he was the head of the department of astronomy at the A. M. Gorky Kharkov State University named after , and taught at the university. According to other sources, the professor was the director of the astronomical observatory of the university in 1919-1930 (certain sources indicate 1917–1937). He also taught at the Emperor Alexander III Kharkov Technical Institute during 1901-1923 (since 1901 to 1914 he was a teacher for hire, taught a course of geodesy), at the Higher Women's Courses during 1908–1913 (he taught spherical trigonometry, was the head of the geodetic office during 1913–1914), at the New Alexandria Institute, Kharkov Institute of National Education, Kharkov Geodetic Institute during 1922-1934, Kharkov Engineering and Construction Institute during 1934-1941, where he lectured on 12 disciplines.

Since 1927 he was a member of the Bureau of Longitude in Leningrad city, in 1928-1933 he was chairman, and later he worked in the Temporary Bureau of the Society of Ukrainian Astronomers, where he was elected in December 1928 at the Congress of the Association of Astronomers of the RSFSR.

In December 1927, together with Parkhomenko P. G. and Ostashchenko-Kudryavtsev B. P. he participated in the observation of a total lunar eclipse.

In 1935, a unified time service was organized under his leadership in Kharkiv city.

In 1935 he was awarded the title of Honored Scientist of the Ukrainian SSR.

In 1936 he was awarded the degree of Doctor of Physical and Mathematical Sciences without the dissertation.

Under the leadership of M. P. Barabashov participated in the expedition, the purpose of which was to observe the total solar eclipse in the area of the station Belorechensk Krasnodar region on June 19, 1936.

Since 1937 he was a member of the Astrometric Commission of the Astrorady of the USSR Academy of Sciences in Pulkovo.

He was a member of the German Astronomical Society.

He was a member of the editorial staff of the Bulletin of Scientific Works of Kharkov Engineering and Construction Institute.

He died on April 5, 1941 in Kharkiv City (according to some data in 1940).

The professor is known for his work in the field of astrometry and astronomy-geodesy. Determined parallax vision and participated in the exploration of the Sun's crown.

In memory of him, his name was called the crater on the Moon.
