Felix Bloch
Felix Bloch (23 October 1905 – 10 September 1983) was a Swiss-American theoretical physicist who shared the 1952 Nobel Prize in Physics with Edward Mills Purcell "for their development of new methods for nuclear magnetic precision measurements and discoveries in connection therewith".
He was the first Stanford University Nobel laureate.
Bloch made fundamental theoretical contributions to the understanding of ferromagnetism and electron behavior in crystal lattices. He is also considered one of the developers of nuclear magnetic resonance.
Bloch was born on 23 October 1905 in Zurich, Switzerland, to Jewish parents, Gustav Bloch and Agnes Mayer. Gustav was financially unable to attend university and worked as a wholesale grain dealer in Zurich. Gustav moved to Zurich from Moravia in 1890 to become a Swiss citizen. Their first child was a girl born in 1902, while Felix was born three years later.
Bloch entered public elementary school at the age of six and is said to have been teased, in part because he "spoke Swiss German with a somewhat different accent than most members of the class". He received support from his older sister during much of this time, but she died at the age of 12, devastating Felix, who is said to have lived a "depressed and isolated life" in the following years. Bloch learned to play the piano by the age of 8 and was drawn to arithmetic for its "clarity and beauty". Bloch graduated from elementary school at twelve and enrolled in the Cantonal Gymnasium in Zurich for secondary school in 1918. He was placed on a six-year curriculum here to prepare him for university. He continued his curriculum through 1924, even through his study of engineering and physics in other schools, though it was limited to mathematics and languages after the first three years.
After these first three years at the Gymnasium, at the age of 15, Bloch began to study at the ETH Zurich. Although he initially studied engineering, he soon changed to physics. During this time, he attended lectures and seminars given by Peter Debye and Hermann Weyl at the ETH Zurich and Erwin Schrödinger at the neighboring University of Zurich. A fellow student in these seminars was John von Neumann.
Bloch graduated in 1927, and was encouraged by Debye to go to the University of Leipzig to study under Werner Heisenberg. Bloch became Heisenberg's first graduate student, and gained his doctorate in 1928. His doctoral thesis established the quantum theory of solids, using waves to describe electrons in periodic lattices.
Bloch remained in European academia, working on superconductivity with Wolfgang Pauli in Zurich; with Hans Kramers and Adriaan Fokker in the Netherlands; with Heisenberg on ferromagnetism, where he developed a description of boundaries between magnetic domains, now known as Bloch walls, and theoretically proposed a concept of spin waves, excitations of magnetic structure; with Niels Bohr in Copenhagen, where he worked on a theoretical description of the stopping of charged particles traveling through matter; and with Enrico Fermi in Rome.
