Arnold Johannes Wilhelm Sommerfeld (German:[ˈaʁnɔltˈzɔmɐˌfɛlt]; 5 December 1868 – 26 April 1951) was a German theoretical physicist who pioneered developments in atomic and quantum physics, and also educated and mentored many students for the new era of theoretical physics.

He served as doctoral supervisor and postdoc supervisor to seven Nobel Prize winners and supervised at least 30 other famous physicists and chemists.

Only J. J. Thomson's record of mentorship offers a comparable list of high-achieving students. He was nominated for the Nobel Prize 84 times, more than any other physicist (including Otto Stern, who got nominated 82 times), becoming the most nominated person to never win the Nobel Prize.

He introduced the second quantum number, azimuthal quantum number, and the third quantum number, magnetic quantum number.^[2&
