Final answer:
The Deaf President Now movement took place in 1988 at Gallaudet University, often linked to the history of the school founded by Dr. Thomas Hopkins Gallaudet. The Americans with Disabilities Act, promoting the integration of people with disabilities into society, was signed by President George H. W. Bush in 1990.
Step-by-step explanation:
The Deaf President Now movement is closely related to the history of the school for the deaf in Washington D.C., which was founded by Dr. Thomas Hopkins Gallaudet.
The movement itself, however, was in 1988 when students at Gallaudet University protested the appointment of a hearing president and demanded a deaf president instead.
The bronze memorial statue for Dr. Gallaudet, seated next to Alice Cogswell using sign language, is a symbol of deaf education but is not directly related to the Deaf President Now movement.
The Americans with Disabilities Act (ADA) signed by President George H. W. Bush in 1990, several years after the Deaf President Now movement, further contributed to the rights and integration of people with disabilities, including those who are deaf or hard of hearing.
