An effort is under way to open up the investigative files on more than 370 New York City schoolteachers who were ousted in the 1950s because of suspected Commmunist ties. Irving Adler, now 96 and living in Vermont, remembers the day he was fired from Straubenmuller Textile High School in Manhattan. "I was teaching a class when the principal sent up a letter he had just received from the superintendent announcing my suspension, as of the close of day."
