In 1871 Anderson worked as an hourly paid teacher at the Gymnasium in Dorpat before
taking up a post as teacher for classical languages at the Gymnasium in Minsk (now in Belarus) in 1872,[5] but he continued his studies of Finno-Ugric languages in his spare time. In 1874, he got married and soon started a family.[3] Nikolai Anderson's three sons were Wilhelm Anderson (born 1880),[7]Walter Anderson (born 1885),[8] and Oskar Anderson (born 1887),[9] who all went on to choose academic careers.
In 1876 Anderson submitted the results of his research, comparing Finno-Ugric and Indo-Germanic languages to the University of Tartu, for which he was awarded a degree in Comparative philology. Still working as a teacher in Minsk, he continued his research, and in 1891 he gained a Magister degree in Comparative Linguistics.[6] In 1892 his mentor Leo Meyer nominated Anderson for an honorary membership of the Learned Estonian Society (Gelehrte Estnische Gesellschaft),[6] a corresponding member of which he had been since 1871,[10] which was granted to Anderson in the same year.
In January 1894 Anderson was offered a professorship in Finno-Ugric languages at the University of Kazan (Russia) to replace Mihkel Veske,[11] which he accepted, as this allowed him to take up an academic career that would allow him more time for his research. As a professor he had the rank of Статский советник (State Councillor), meaning that he held personal nobility in the Imperial Russian hierarchy.[6]
In 1898 Anderson fell ill with a nervous disorder and was hospitalized for several months in Tartu. In 1904 he relapsed and was once again hospitalized. After his condition improved in early 1905 he visited his sister in Narva, where he fell ill with pleurisy and died shortly thereafter.[6] Anderson was buried with his parents in Yamburg.[3][6][12]
