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.
Paul Samuelson Paul Anthony Samuelson (May 15, 1915 – December 13, 2009) was an American economist and the first American to win the Nobel Memorial Prize in Economic Sciences. The Swedish Royal Academies stated, when awarding the prize in 1970, that he "has done more than any other contemporary economist to raise the level of scientific analysis in economic theory". Economic historian Randall E. Parker calls him the "Father of Modern Economics", and "The New York Times" considered him to be the "foremost academic economist of the 20th century".
