Ivan Pavlov (1849–1936) In his laboratory, Pavlov was known for his meticulous organization, keen memory, and attention to details (Windholz, 1990). But outside his lab, Pavlov was absent-minded, forgetful, and impractical, especially regarding money. He often forgot to pick up his paycheck, and he sometimes lent money to people with hard-luck stories who couldn’t possibly pay him back (Fancher, 1996). On a trip to New York City, Pavlov carried his money so carelessly that he had his pocket picked in the subway, and his American hosts had to take up a collection to pay his expenses (Skinner, 1966).
