Gerardus 't Hooft spends his childhood in The Hague - the seat of government of the Netherlands - with his parents, and his two sisters.

Gerardus 't Hooft marries Albertha Schik (Betteke) who studies medicine at Utrecht University. They have two daughters, Saskia and Ellen.

Gerardus 't Hooft is awarded the Nobel Prize in Physics along with his PhD advisor Martinus Veltman "for elucidating the quantum structure of electroweak interactions in physics."

Gerardus 't Hooft is Morris Loeb Lecturer at Harvard University, Cambridge, MA, USA. There, he works on chromodynamics, especially on the problem of quark confinement.

Gerardus 't Hooft is Guest Professor at Duke University, Durham, NC, USA.

After primary school, Gerardus 't Hooft attends the Dalton Lyceum at The Hague, which applies the ideas of the Dalton Plan. There, students are given extra hours for studying homework material with the teachers. This method suits 't Hooft very well. He easily passes his science and mathematics exams. 't Hooft also passes his classes in English, French, German, classical Greek and Latin with some struggles. At the age of 16, he earns a silver medal in the second Dutch Math Olympiad.

Gerardus 't Hooft becomes Full Professor at Utrecht University. In these years he turns to the study of quantum gravity and explores theories alternative to superstring theory such as the "holographic principle."

Gerardus 't Hooft's full Professorship at Utrecht University is turned into a Royal Dutch Academy of Sciences (KNAW) position.

Gerardus 't Hooft is fellow at CERN, Geneva. Veltman also is there and they can refine their renormalization method. 't Hooft works on the extension of the Yang-Mills theory to include quark asymptotic freedom, but does not publish his discovery.

At the age of eight, Gerardus 't Hooft's family moves for a ten month's period to London, England, where for the first time 't Hooft is forced to master a foreign language, English.

Gerardus 't Hooft is Guest Professor at Boston University.

Gerardus 't Hooft is born in Den Helder, the Netherlands. He is the middle child of a family of three. He comes from a family of scholars. His grandmother is a sister of the Nobel prize laureate Frits Zernike. His uncle Nicolaas 'Nico' van Kampen is professor of theoretical physics at Utrecht University. His father is also a scientist working as a naval engineer.

Gerardus 't Hooft is Sherman Fairchild Distinguished Scholar at Caltech, Pasadena, CA, USA.

Gerardus 't Hooft takes his Bachelor's in Physics and Mathematics at Utrecht University. Since he is interested in particle physics, his undergraduate thesis advisor becomes Martinus Veltman. Thanks to Veltman's advices, 't Hooft begins working on theoretical particle physics and Yang-Mills fields. His assignment is to study the so-called Adler-Bell-Jackiw anomaly. Gerardus 't Hooft passes his "Doctoral examen" in Theoretical Physics, in October 10, 1969.

Gerardus 't Hooft chooses as the topic of his dissertation the subject on which his advisor Veltman is working: the renormalization of the Yang-Mills theory. According to Veltman, the Yang-Mills theory is fundamental for the understanding of both the weak and the strong interactions. Before he obtains his PhD, 't Hooft is successful in renormalizing the electroweak theory based on the Yang-Mills theory and the Higgs mechanism. This achievement will gain him the Nobel Prize.

Gerardus 't Hooft spends the summer studying at the Advanced Science Institute established by the French physicist Maurice Lévy at Cargèse, a small town on the French island Corsica.

Gerardus 't Hooft is Assistant Professor at Utrecht University.

Gerardus 't Hooft works at the SLAC, Stanford, CA, USA. He studies the effect of instantons in quantum chromodynamics. By means of this approach, it is possible to derivate finite and well-defined contributions to the amplitudes, and many riddles in the experimental data concerning chiral symmetry are finally resolved, including the problems with the eta particle.
