Interlingua
Alice Vanderbilt Morris and her husband, Dave Hennen Morris had become interested in linguistics and the international auxiliary language movement in the early 1920s. In 1924 they created the non-profit International Auxiliary Language Association (IALA) in New York City. They wanted to give scientific support to the study of IALs. They asked for the help of linguists like Edward Sapir, William Edward Collinson, and Otto Jespersen.
