James Sanborn is a Washington, D.C.-born artist with a Bachelor of Arts degree from Randolph-Macon College and a Master of Fine Arts from Pratt Institute. Sanborn is noted for his work with American stone and related materials that evoke a sense of mystery and the forces of nature. To produce the code for "Kryptos," Mr. Sanborn worked for four months with a retired CIA cryptographer to devise the codes used in the sculpture. Mr. Sanborn wrote the text to be coded in collaboration with a prominent fiction writer.
