Gallaudet Trivia

What year did the Columbia Institution for the Deaf change its name to Gallaudet College by an Act of Congress (Public Law 420)?

Answer: June 18, 1954  ---  90 years after the signing of the Congressional charter by US President Abraham Lincoln that authorized and enacted a college for the deaf on April 8, 1864. 

Before 1954, the Columbia Institution for the Deaf was comprised of both Gallaudet College and Kendall School for the Deaf.  In 1986 Gallaudet College becomes Gallaudet University when President Ronald Reagan signs the Education of the Deaf (Public Law 99-371).

In 1996, Pre-College National Mission Program was formed as an umbrella to cover the University's preschool programs, the Kendall Demonstration Elementary School, the Model Secondary School for the Deaf, other pre-college research and teaching units, and all their associated buildings and other facilities.  It is renamed the Laurent Clerc National Deaf Education Center in 2000.
