Read the following article and select the best answer. Article: American sign language has an interesting history. Although there have always been deaf individuals in America, the history really begins in 1817. Before 1817 deaf people communicated by using "home signs". Gestures were individually created and used within the home for simple communication. There were no schools or formal sign language training for the deaf. So, why was 1817 an important date? Well, the story begins with Thomas Hopkins Gallaudet. Gallaudet met his neighbor's daughter Alice Cogswell. Alice was the young deaf daughter of Dr. Mason Cogswell from Hartford, Connecticut. Gallaudet began teaching Alice to read and write a few simple words. Excited by the success Dr. Cogswell encouraged Gallaudet to establish a school for the deaf. Cogswell raised the money and Gallaudet traveled to Britain to learn the methods used there. However, the schools refused to share their instructional techniques and methods. While in London, there happened to be a demonstration of the French method of deaf education. Britain was using an oral method of instruction; however, the French method used signs. Gallaudet was fascinated with the method and was able to meet with the instructor, Sicard, and his two deaf pupils, Jean Massieu and Laurent Clerc. Sicard agreed to teach Gallaudet his method and Gallaudet went to Paris to learn French signs. After a while, Gallaudet wished to return home and convinced Clerc to go with him and help him establish the school. The trip home was a 52-day voyage during which Clerc taught Gallaudet French signs and Gallaudet taught Clerc English. On April 15, 1817, Laurent Clerc and Thomas Hopkins Gallaudet established what is currently known as the American School for the Deaf in Hartford, Connecticut. The opening of the first school for the deaf can be viewed as one of the most important events in current deaf culture.
