Joan Fischer Targ (July 8, 1937[1][2] – June 2, 1998) was an American educator who was an early proponent of computer literacy and initiated peer tutoring programs for students of all ages.
[4][5] After living in several cities in various parts of the United States, in 1948, the family moved to Brooklyn, where Regina worked as an elementary school teacher and nurse.
[13] She coauthored the book Ready, run, fun: IBM PC edition with Jeff Levinsky.
In 1976, she, her husband, and another family bought 80 acres of land in Portola Valley, and they hoped to turn it into another such farm; a lawsuit from her neighbors attempting to block this use was settled in her favor shortly before her death.
[6][7][8] In the 2014 Bobby Fischer biopic Pawn Sacrifice, Targ was portrayed by Lily Rabe, with Sophie Nélisse appearing as the teenage Joan.
