The father of scientist Walter Alvarez recived a Nobel Prize in Physics in what year?
3581 Alvarez 3581 Alvarez (1985 HC) is a Mars-crossing asteroid discovered on April 23, 1985, by Shoemaker, C. and Shoemaker, E. at Palomar. Based upon lightcurve data, it has a synodic rotation period of  hours with an amplitude variation of in magnitude. With a diameter of ~14 km, it is one of the largest Mars-crossing asteroids. However, due to the high inclination of its orbit, it never actually passes through the orbit of Mars since at perihelion it is well away from the plane of Mars' orbit. The asteroid is named after planetary scientist Walter Alvarez and his Nobel-prize winning father, physicist Luis Alvarez.
Philip Warren Anderson Philip Warren Anderson (born December 13, 1923) is an American physicist and Nobel laureate. Anderson has made contributions to the theories of localization, antiferromagnetism, symmetry breaking (including a seminal paper in 1962 discussing symmetry breaking in particle physics, leading to the development of the Standard Model around 10 years later), and high-temperature superconductivity, and to the philosophy of science through his writings on emergent phenomena.
