Human rights

Desegregation of Howard County Schools

The Howard County School Board had pursued a policy of voluntary integration prior to 1964, which resulted in only a fraction of black students attending white schools. As late as 1964, ten years after Brown v. Board of Education, the board stated that it would not consider forcing integration until 1967, to "allow for a reasonable period of adjustment" to the change. However, in May 1964, as the county experienced increasing growth, the board was expanded to five members, and Cochran was appointed as one of the board's new members. He is credited by Maryland State Senator Robert Kittleman, then the education chairman of Howard County's NAACP chapter, for providing the swing vote on February 9, 1965, to close all-black schools.

In 1975, as County Executive, Dr. Cochran introduced an act establishing an Office of Human Rights and making discrimination on the basis of race, creed, religion, physical or mental handicap, color, sex, national origin, age, occupation, marital status, political opinion, sexual orientation, or personal appearance in the areas of housing, employment, law enforcement, public accommodations, and financing unlawful in Howard County Maryland.
