Sergiusz Graf von Toll (22 November 1893 – 19 December 1961) was a Polish entomologist who specialised in microlepidoptera and particularly Coleophoridae.[1] He was a member of the Polish Academy of Sciences.[2]


Toll was born on 22 November 1893 in Warsaw,[3] the son of Alexander Toll and his wife Adelaide (or Anna). He had four elder brothers and sisters. He came from a noble family; his great-grandfather, General Karol Toll, was made a count by Nicholas I of Russia and the family owned Uniejów Castle at Łódź Voivodeship in central Poland. He received his schooling in Warsaw and went to the University of Warsaw where he studied law. During World War I, the university was evacuated to Rostov-on-Don in Russia, and while there, he added biology to the subjects he was studying. In 1918, he was awarded his PhD in law.[4][5] He had already developed his interest in butterflies and moths and while in Russia he studied the lepidoptera of the Rostov region.[6]
