Editing Baltimore Polytechnic Institute (section)

=== Relocation ===
Due to continued growth of the student population of the City's Public Schools system in the early 20th century and especially in the growing demand for higher secondary education at high schools like at the B.P.I.and the rival B.C.C. and the two girls high schools of Eastern and Western, the City's technical school relocated after a long public campaign for larger better facilities ten blocks further north from downtown in 1913 to [[St. Paul Street-Calvert Street#Calvert Street|Calvert Street]] and [[North Avenue (Baltimore)|North Avenue]] (formerly known as Boundary Avenue, of the old City / County line of 1818–1888. The former old 1860s era converted mansion of [[Second Empire architecture|French Second Empire]] style architecture of the former [[Maryland School for the Blind]] was purchased. It was sitting on a slight hill above the avenue in a then rural / suburban setting. Two additional massive three-story wings on the east and west sides of the center mansion were constructed and added by the City with a [[Greek Revival architecture|Greek Revival]] architecture 
with  Classical style columns on the front facade. Now for the first time in its 30 years history "Tech" had a suitable building expansive enough to handle both its academic and technical education requirements. But the growth of "The Institute" was so much that in only a decade and a half by 1930, the old original central wing of "The Mansion" from the Blind School was razed after only 17 years and replaced by a simpler center three-story wing between the two flanking earlier 1913 structures with an additional large enormous auditorium / gymnasium in a further east wing facing North Avenue and towards adjacent Guilford Avenue were constructed. This massive assembly hall and physical education building with swimming pool was the largest built at the time in the city and the auditorium served many secular / civic / cultural occasions and events in town for decades into the mid-1980s. While at this location, the high school expanded both its academic, technical and athletic programs under the extensive longtime leadership of legendary Dr. Wilmer Dehuff, who was the fourth principal from 1921 to 1958.

Principal Dehuff despite his many accomplishments in his long educational career and his devotion and love of Poly, unfortunately in his view opposed and reluctantly (see below) oversaw the [[racial integration]] of the technology high school in September 1952, the first instance in the [[Southeastern United States|American Upper South]] region with the City of Baltimore public schools admitting African-American – then called "Negro" 
/ "Colored" students. The Baltimore City Public Schools (founded 1829), had maintained racially segregated schools since first beginning public education for its black minority in Baltimore in 1870. The nationally famous precedent occurred two years before the rest of the nation took up this serious issue of inequality and discrimination addressed finally by the [[Supreme Court of the United States]] in May 1954 in the famous case of ''[[Brown vs Board of Education|Brown vs. Board of Education of Topeka, Kansas]]''. Previous black students in Baltimore City (and from adjacent [[Baltimore County]] also) had attended the [[Frederick Douglass High School (Baltimore, Maryland)|Frederick Douglass High School]] (formerly named the "Colored High School" up to 1923 – second oldest in the nation – founded the same year as Poly – 1883) on the westside of town and the later opening [[Paul Laurence Dunbar High School (Baltimore, Maryland)|Paul Laurence Dunbar High School]] in East Baltimore.<ref>Templeton (Winter 1954), p. 22-29</ref><ref>Thomsen (Fall 1984), p. 235-238</ref> Dr. Dehuff later after his retirement in 1958 and  his 37 years career at the Polytechnic Institute, became the president and dean of faculty at the then private institution, the [[University of Baltimore]] on Mount Royal Avenue.
