Paul Erdős, the most prolific mathematician of all time, was known for his nomadic lifestyle and being a terrible houseguest. Despite this, he produced over 1,500 academic publications, making him the most published mathematician in history. One of his notable contributions was the probabilistic method, which revolutionized the approach to proving the existence of mathematical objects. Erdős believed in math as a social activity and collaborated with countless researchers, leading to the creation of the Erdős number, a measure of authorship distance. He is remembered not only for his publications but also for his generosity and his knack for asking important math questions. Erdős passed away at a math conference, doing what he loved.
