  During the time of Peirce’s teaching logic at Johns Hopkins University, that is: during the years from 1879 through 1884, Peirce had a number of students in logic who then went on to establish significant reputations in their own right. Often mentioned in this connection are John Dewey, Allan Marquand, Christine Ladd-Franklin, Oscar Howard Mitchell, Benjamin I. Gilman, Fabian Franklin, and  Thorstein Veblen. Here we provide brief descriptions of three of these students, Dewey, Ladd-Franklin, and Mitchell. Of necessity the accounts given here of the work of these students will be extremely brief. It is obvious that full-length accounts of each of them can be given, and in the case of one of them, John Dewey, full-length accounts have, indeed, often been given.
