Benjamin Samuel Bloom (February 21, 1913 – September 13, 1999) was an American educational psychologist and didactician who made contributions to the classification of educational objectives and to the theory of mastery learning. He has greatly influenced the practices and philosophies of educators around the world from the latter part of the twentieth century.

Perhaps his most significant contribution to the field of education was developing a comprehensive system of describing, assessing and classifying educational outcomes, now known as Bloom's taxonomy.
