Benjamin Bloom was an American educational psychologist known for developing Bloom's Taxonomy, a classification of learning objectives identifying different levels of cognition. He led a group of educational psychologists in the 1950s to develop a comprehensive system for describing and assessing educational outcomes. Bloom's Taxonomy remains influential for educators worldwide by providing a structure for classifying intellectual behavior important to learning.

4. HIS WORKS
In 1956, Bloom edited the first volume of The Taxonomy of Educational
Objectives: The Classification of Educational Goals, which classified learning
objectives according to a rubric that has come to be known as Bloom's
Taxonomy. It was one of the first attempts to systematically classify levels of
cognitive functioning and gave structure to the otherwise amorphous mental
processes of gifted students. Bloom's Taxonomy remains a foundation of the
academic profession according to the 1981 survey, "Significant Writings That
Have Influenced the Curriculum: 1906–81" by Harold G. Shane and the National
Society for the Study of Education. Bloom's 2 Sigma Problem is also attributed
to him.
