, where he consecutively assumed positions of an assistant at the Cabinet of His Imperial Majesty, chief clerk of the Mining Department, senior aide and the staff officer Corps of Mining Engineers. In 1834, he was promoted to the rank of captain and in 1845 to colonel. The next year he was appointed as Chief of Staff of the Corps of Mining Engineers and remained in that position until 1861. While remaining Chief of Staff, he began teaching at Saint Petersburg Mining Institute

He took a three-months sabbatical leave in 1862 to attend an international scientific exhibition in London and died later in 1870. Samarsky–Bykhovets was a highly decorated officer with an impeccable career list.

Relation to samarskite

Samarsky–Bykhovets himself was not involved in the studies of samarskite and samarium. As a mining official, he merely granted access to mineral samples from the Urals to the German mineralogist Gustav Rose
Gustav Rose
Gustav Rose was a German mineralogist who was a native of Berlin. He was a brother of mineralogist Heinrich Rose , the son of pharmacologist Valentin Rose , and the father of noted surgeon Edmund Rose and the classicist Valentin Rose.He was a graduate of the University of Berlin, where he was a...

. Rose in 1839 described a new mineral in those samples and named it uranotantalum believing that its composition is dominated by the chemical element tantalum
