"The prominence of Watson and Crick and the Phage Group made Baltimore all the more desperate to do some real experimental biology. During the spring of his junior year, Baltimore became president of the Biology Club and enrolled in a microbiology seminar that discussed the advances of Luria, Delbrück, Lederberg, and others. But he was sick of just talking about biology. He had understood very quickly that designing and completing experiments were the accomplishments that make a biologist; gathering an encyclopedia knowledge of facts simply makes a good student."
