Who chaired the house committee on un-American activities?

The House Committee on Un-American Activities (HUAC) was notably chaired by Congressman Martin Dies Jr. from Texas during its early years, particularly in the late 1930s and early 1940s. The committee was established to investigate alleged disloyalty and subversive activities among American citizens, particularly during the Red Scare. Over the years, different members of Congress served as chairpersons, but Dies is often recognized as one of the most prominent early leaders of the committee.
