In October 1958, Catholics of the Dayton area pledged $4,953,050 to help pay the costs of building Catholic high schools in the area. Among the schools built with this money were Archbishop Alter High School and its mirror image, Carroll High School, built the previous year. Development of Alter High School was led by Reverend Paul F. Leibold, and, at the request of the people, the school was named after Archbishop Karl Alter. Archbishop Karl Alter was born on August 18, 1885, and died on August 23, 1977.
