Autograph letter signed, 3 1/2 pages (on two conjoined sheets - both sides), 5,5 x 8,5 inch, `Prof. Dr. P. Zeeman` letterhead, Amsterdam, 30.04.1933, to Samuel A. Goudsmit - thanking the recipient for sending a copy of his book on Atomic Energy States, written and signed in dark ink "P. Zeeman", with a horizontal letter fold and pinholes to the upper left corner - in fine to very fine condition.
In parts (translated):
"[...] The book will be very useful. It is more useful on the issue than the Tables Annuelles. Subsequent editions of your and Bacher's book will prove to be indispensable [...] Did you see Zwikker's book, the Leerboek der Optiek? It is written in a refreshing and vivid way. It is too bad that the magnetic splitting has been treated completely wrong and even by a student of mine! I am already having some pleasure from a mass spectrograph that I installed following Thomson's parabola method. By experiment I can indeed prove that [...] the percentage H1 H2 had increased by fractionated evaporation and rectification. He found the specific gravity of the gas obtained through his method the specific gravity of the gas obtained through his method to be 1.51-+ 0.005% higher than that of ordinary hydrogen. With the mass spectrogram you see immediately that H2 has to be present. [...] Recently we had Francis Perrin to visit. Very interesting. Holweck was going to come too, but he had to leave for Algiers to do gravity measurements for a governmental commission. Now we are waiting for Geiger to visit us on the 11th of May [...]"

Profession:
(1865 - 1943) Dutch physicist who shared the 1902 Nobel Prize in Physics with Hendrik Lorentz for his discovery of the Zeeman effect
Year of Birth: 1865
Pieter Zeeman (1865-1943) was a Dutch physicist who was awarded the Nobel Prize in Physics in 1902 for his discovery of the Zeeman effect. He was born in Zonnemaire, Zeeland, Netherlands on May 25, 1865, and grew up in a rural area of the Netherlands. Zeeman was the oldest of seven children and his parents were Pieter Zeeman and Saartje van der Woude. His father was a minister in the Dutch Reformed Church.
Zeeman was an excellent student and showed an interest in science from a young age. He studied mathematics and physics at the University of Leiden and graduated in 1885. He then went on to pursue a doctorate in physics at Leiden, which he received in 1891 with a thesis on the magnetization of light and the induced polarization in its spectrum. This thesis was the basis for his Nobel Prize in Physics. After completing his doctorate, Zeeman took a job as a lecturer at the University of Amsterdam in 1893.
Zeeman's most famous work was his discovery of the Zeeman effect, which demonstrated that a magnetic field could alter the spectral lines of a light source. This discovery led to the development of quantum mechanics, and Zeeman was awarded the Nobel Prize in Physics in 1902 for his work. He also worked on an atomic model of the atom, which led to the development of the Bohr model. He also worked on the theory of relativity and the structure of the atom.
In addition to his scientific work, Zeeman also held various positions in academia and was a professor at the University of Amsterdam from 1901 to 1910. During this time he also wrote several books on physics, such as The Dynamics of Electrons in Magnetic Fields. He also wrote several popular books on science, such as The Laws of the Electron.
In addition to his scientific endeavors, Zeeman was also an active member of the Dutch scientific community. He was a founding member of the Royal Netherlands Academy of Arts and Sciences and served as its president from 1923 to 1925. He was also a member of the International Union of Pure and Applied Physics, and served as its president from 1927 to 1929.
Pieter Zeeman died on October 9, 1943 in Amsterdam, Netherlands. He was 78 years old. He was a highly influential scientist who made significant contributions to the development of quantum mechanics and the atomic model of the atom. He is remembered as one of the most influential physicists of the twentieth century.
