Utrecht University celebrates 80th birthday Gerard ’t Hooft

This summer marks a special milestone for Nobel laureate Gerard ’t Hooft, who recently turned 80. To celebrate his life and groundbreaking contributions to theoretical physics, family, friends and colleagues will gather in Leersum on 27 and 28 August. The celebration will feature talks by renowned speakers, including American Nobel laureate Frank Wilczek and Professor Robbert Dijkgraaf, former Dutch Minister of Education, Culture and Science.

Gerard ’t Hooft is one of the most influential theoretical physicists of his generation. He fundamentally reshaped our understanding of quantum forces and was awarded the 1999 Nobel Prize in Physics, together with Martinus Veltman, for their groundbreaking work on the quantum structure of electroweak interactions.

His influence has endured across a broad range of fields in physics, from black holes to subatomic particles. He has supervised and mentored generations of PhD candidates, helped shape the careers of countless physicists, and extended his influence beyond academia through accessible books, essays and engaging public lectures.

Gerard 't Hooft is, in many ways, a living embodiment of what a university is supposed to be

Reflecting on ‘t Hooft’s influence

The two-day celebration in honour of his 80th birthday will take place in Leersum and bring together one hundred guests, including family, friends and colleagues. The programme features talks by internationally renowned speakers, who will share personal anecdotes about ’t Hooft and reflect on the ways his work has influenced their own. Among them is Professor Dijkgraaf, who obtained his doctorate under ’t Hooft’s supervision and has since built an outstanding academic and political career of his own.

The event was organised by the Institute of Theoretical Physics and the Department of Physics at Utrecht University, in collaboration with the Dutch Research School of Theoretical Physics.

Living embodiment of Utrecht University

Gerard ’t Hooft has been associated with Utrecht University for half a century and remains an active member of its academic community. It is therefore fitting that Wilco Hazeleger, Rector Magnificus of Utrecht University will attend the celebration.

“Gerard ’t Hooft is not only one of the greatest minds of Utrecht University's Faculty of Science,” Hazeleger says. “He is, in many ways, a living embodiment of what a university is supposed to be, and of what Utrecht University stands for: ambition, engagement, inspiration and independence.”

Multifaceted personality

To further celebrate his life and work, a new website dedicated to ’t Hooft was recently launched. It highlights not only his scientific achievements, but also his multifaceted personality. Alongside his scientific accomplishments, ’t Hooft is a talented pianist, a pioneer of early computer animation and graphics, and a witty writer, as demonstrated by his humorous essays on subjects ranging from the apostrophe in his name to the constitution and bylaws of the asteroid named after him.

Among his many accolades, ’t Hooft naturally mentions the Nobel Prize. But he also enjoys pointing to more unusual honours, such as a pizza named after him at a restaurant in Sofia, Bulgaria. It is a fitting example of his appreciation for recognition that comes not only from the scientific community, but from society at large.
