Mereology is the theory of part (and hence, by implication, of whole also). Systematic work on these topics was produced in 1916 by the Polish philosopher S. Leśniewski; his paper on the general theory of sets was in that year published in Moscow. My own acquaintance with the theory is due to the teaching of Czesław Lejewski, who studied under Leśniewski.
