Thomas Joseph (a nom de plume) is a puzzle creator and author of more than thirty-five crossword puzzle books. In his introduction to one of his popular large-print crossword books he declares, "Even though your vision isn't 20-20, you can still benefit from a good brain workout." With that in mind, Joseph has authored over a dozen jumbo and large-print crossword books with Puzzlewright Press, many of which have been approved by the NAVH (National Association for Visually Handicapped).
