Biography:
He was born on December 22, 1885, according to the Julian calendar, or January 3, 1886, according to the Gregorian calendar, in the Tiflis city of the Russian Empire (now Tbilisi, Georgia).
In 1910 he graduated from St. Petersburg Imperial University.
From 1910 he worked at the Pulkovo Observatory.
During 1912-1922 and 1925-1941 he worked in the Simeiz branch of the Pulkovo Observatory, which he headed during 1925-1931 and 1936-1941.
Since 1944, the astronomer has been the director of the Pulkovo Observatory.
On June 10, 1945, the astronomer was awarded the Order of the Red Banner of Labor.
He died on December 17, 1946 in Leningrad (now St. Petersburg).
In Simeiz he organized the first systematic observations of small planets of the solar system in modern Ukraine. He discovered 74 small planets and 7 comets in his lifetime, and in 1913 he was the first in the Russian Empire to discover a comet, 13 variable stars, according to K. D. Pokrovsky.
He was engaged in calculating the orbits of comets, developed a method of taking into account the terms of higher orders in the calculation of perturbations. He paid special attention to one of the comets he discovered - the short-period comet 25D/Neujmin, discovered by an astronomer on February 24, 1916. He performed micrometric measurements of Neptune's moons. The scientist also conducted micrometric observations of binary stars, determined the proper motions of stars.
At the initiative of the astronomer, the Pulkovo Observatory took part in the international program of the German Astronomical Society for Repeated Observations of Sky Zones for the Astronomische Gesellschaft or AG catalog.
He was a laureate of the Russian Astronomical Society Prize, and also received 6 medals from the Pacific Astronomical Society for the discovery of comets.
In honor of the astronomer were named the lunar crater Neuimin, the small planet (1129) Neuimin, discovered by P. G. Parkhomenko August 8, 1929 at the Simeiz Observatory, and the Neuimin Plain on small planet (951) Gaspra discovered by him in 1916.
