Gallaudet School is a symmetrical Collegiate Gothic building of red-brown brick raised on a rusticated limestone base. A three-story central frontispiece faced in carved stone steps forward between two-story wings; "Gallaudet" and "School for the Deaf" are incised across a stone band above three Tudor-arched windows. The upper walls are laid in diamond diaper patterns, and the wings terminate in battlemented pavilions with stone-coped parapets, tall paneled pinnacle-buttresses, and carved armorial shields. Tudor-arched stone surrounds frame the tall classroom windows, and slate hipped roofs cover the flanking ranges.
The St. Louis Board of Education built Gallaudet School in 1925 on South Grand Boulevard as a day school for deaf children within the public school system. Rockwell Milligan designed it. The school carried the Gallaudet name — shared with Gallaudet University in Washington — after Thomas Hopkins Gallaudet, a founder of deaf education in the United States. It taught deaf and hard-of-hearing students academic subjects alongside art, music, physical education, and industrial arts. The St. Louis Public Schools closed Gallaudet in 2012.
