The surname SCZEPANSKI originated in Poland, likely in the 14th or 15th century. It is derived from the Polish personal name Szczepan, which is a Slavic form of the Latin name Stephanus or Stephen. The name Szczepan comes from the Polish word "szczep," meaning "stem" or "stock," referring to the origin or roots of a family line.

In the 19th century, a prominent SCZEPANSKI was Stanisław SCZEPANSKI (1836-1912), a Polish mathematician and professor at the University of Warsaw. He made significant contributions to the field of analysis and wrote several influential textbooks on mathematics that were widely used in Polish universities.
The SCZEPANSKI surname can also be found in various historical records and documents from different regions of Poland, such as land registers, church records, and census data from the 18th and 19th centuries.
