||Artifact belonged to William Preston Holly (1893-1961) who was blind and learned to use the slate as a student at the Florida School for the Deaf and the Blind, St. Augustine, in 1904. He continued to use it in his business as a curb market vendor. After his death, Holly's slate went to his daughter, Buelah Brazzell. Originally called an Arabic Slate, this style of math aid was developed in Paris, France in the 19th century. One source from 1910 called it the Paris Method. APH developed its own model, known as an Arithmatic Type Frame, in 1936 at APH.
