Nicholas Sanduleak (Romanian: Nicolae Sanduleac June 22, 1933 in Lackawanna, New York, United States – May 7, 1990) was an American astronomer.
His family moved to Cleveland soon after he was born, where Sanduleak did undergraduate work at the Case Institute of Technology, receiving a B.S.
After serving in the Army, Sanduleak came back to Case Institute, receiving a master's degree in 1961 and a doctorate in 1965.
[1][2] Sanduleak was a spectroscopist who worked on a number of very large objective prism surveys.
He was the first to discover metallicity differences between the Small and Large Magellanic Clouds, and wrote papers about a number of spectroscopically interesting objects.
