Jan Mikusiński was a Polish mathematician based at the University of Wrocław known for his pioneering work in mathematical analysis. Mikusiński developed an operational calculus – known as the Calculus of Mikusiński, which is relevant for solving differential equations.

From the convolution product he goes on to define what in other contexts is called the field of fractions or a quotient field. These ordered pairs of functions Mikusiński calls operators – Mikusiński Operator. He is also well known for Mikusinski's cube and Antosik–Mikusinski theorem, and Mikusinski convolution algebra.
