The board of trustees announced a new faculty pay scale for 1956-57, providing increases of up to 23 percent.  Based on a study of pay inequities relative to the consumer price index from 1939 to 1956, the new scale, which included full pension benefits in place of one-half pension benefits, addressed inequities which, the survey showed, were greatest in the upper ranks—professors and associate professors.  With the pension benefits, the new top salaries were $5,655 a year for instructors, $6,460 for assistant professors, $7,495 for associate professors and $13,015 for professors and represented increases of 11, 16, 20 and 23 percent, respectively.      The New York Times
