Ivan Manuilovich Neudatchin moved as a baby of one year to Ashkabad in Turkmenistan, from where he returned to his birth city to graduate as a civil engineer from the Saint Petersburg Polytechnic School in 1917. After the Russian October Revolution he moved to Vladivostok first and from there to Harbin, China. He continued in 1922 to Berkeley, California, where he obtained a second degree in civil engineering. There, he changed his name also to Nelidov. From 1929 to 1943, he was an engineer with the Department of Public Works, State of California, where he was responsible for dams erected recently, and for novel computational methods for gravity and arch dams. After World War II, Nelidov worked in earthquake engineering in Oakland CA. Nelidov concluded his career by designing the Bay Area Rapid Transit BART station in Berkeley, and the Rockridge Station in Oakland.

Nelidov presented his Master Thesis on Scouring below dams at the University of California, Berkeley. The Special Committee on irrigation hydraulics was composed of individuals so famous as B.A. Etcheverry, J. Hinds, R.A. Monroe, R.L. Parshall, and F.C. Scobey. Later, Nelidov contributed mainly discussions to original papers of the Transactions of the American Society of Civil Engineers ASCE, first on structural problems relating to dams erected in California, then also to hydraulic problems relating to dam design. The first referred to the hydraulic jump, in which Nelidov's contribution points to works conducted by Vladimir Ivanovich Aravin (1900-1980) in Russia. Other discussions refer to the hydraulic behavior of siphons, and the stability of gravity dams. Nelidov was an ASCE Member from 1927, and promoted to Fellow in 1959.
