In 1948, along with Stanford University professor Paul Kirkpatrick (1894–1992), Baez developed the X-ray reflection microscope for examination of living cells. This microscope is still used today in medicine. Baez received his PhD in physics from Stanford in 1950. ... As the Cold War arose in the 1950s, Baez's talents were in high demand for the developing arms race. However, influenced by his family's pacifist beliefs, he refused lucrative war industry jobs, preferring instead to devote his career to education and humanitarianism.
Linda Ronstadt's great grandfather, graduate engineer Friedrich August Ronstadt (who went by the name Federico Augusto Ronstadt) immigrated to the West (then a part of Mexico) in the 1840s from Hanover, Germany, and married a Mexican citizen, and eventually settled in Tucson.
This is a reminder of that weird phenomenon I've pointed out a number of times: back when there were about an order of magnitude fewer Mexican-Americans, there were about as many famous Mexican-Americans (Pancho Gonzalez, Lee Trevino, Nancy Lopez, Anthony Quinn, etc.) as there are today. The conventional wisdom says there should now be two orders of magnitude more high achieving Mexican-Americans today, because of Discrimination and Prejudice in the past, but it doesn't actually seem to work that way.
