I want to know the answer to the following question:
What date did Thomas Watson, Jr. send out a letter about IBM hiring the best people regardless of race, gender, or origin?
All the background I'm provided with is that "He also publicized the policy so that in his negotiations to build new manufacturing plants with the governors of two states in the U.S. South, he could be clear that IBM would not build "separate-but-equal" workplaces.". Is that enough to answer the question?
Answer: no
