Paul Schulze was "the most important German tick taxonomist of the early 20th century."[1] Between 1929 and 1937, he described 19 genera, 17 subgenera, 150 species and 150 subspecies of ixodid ticks.[2][1][3] He was essentially an amateur taxonomist, working alone for most of his career, not consulting the major tick collections or collaborating with other tick taxonomists.[3]
