I want to know the answer to the following question:
In what year was IBM's first equal opportunity policy letter published?
All the background I'm provided with is that "In 1952, Thomas J. Watson, Jr., published the company's first written equal opportunity policy letter, one year before the U.S. Supreme Court decision in Brown vs. Board of Education and 11 years before the Civil Rights Act of 1964.". Is that enough to answer the question?
