Lomonosov returned to Russia in June 1741, after being abroad 4 years and 8 months. A year later he was named an Adjunct of the Russian Academy of Science in the physics department. In May 1743, Lomonosov was accused, arrested, and held under house arrest for eight months, after he supposedly insulted various people associated with the Academy. He was released and pardoned in January 1744 after apologising to all involved.
Lomonosov was made a full member of the Academy, and named Professor of chemistry, in 1745. He established the Academy's first chemistry laboratory.[18] Eager to improve Russia's educational system, in 1755, Lomonosov joined his patron Count Ivan Shuvalov in founding Moscow University.[18]
In 1760, he was elected a Foreign Member of the Royal Swedish Academy of Sciences. In 1764, he was elected Foreign Member of the Academy of Sciences of the Institute of Bologna[19] In 1764, Lomonosov was appointed to the position of the State Councillor which was of Rank V in the Russian Empire's Table of Ranks. He died on 4 April (o.s.), 1765 in Saint Petersburg. He is widely and deservingly regarded as the "Father of Russian Science",[20] though many of his scientific accomplishments were relatively unknown outside Russia until long after his death and gained proper appreciation only in late 19th and, especially, 20th centuries.
