Biography on the Official Web Site of the Nobel Prize


Man has always been fascinated by the stars, mapping them and calculating our place in the heavens. Since the birth of the Big Bang theory almost a century ago, man’s desire to unravel the ever-expanding universe has grown.

It was that desire that led Brian Schmidt to win the Nobel Prize. He shares half the award with his American colleague Adam Riess. The other half was awarded to Saul Perlmutter, also American, whose team was working in the same field. What the three men (and their associated teams) discovered was that the universe’s rate of expansion, far from slowing down as you might expect billions of years after the Big Bang, is actually accelerating. In doing so they confirmed a theory first considered by Albert Einstein in 1917 but which he dismissed as being so unlikely that he dubbed it his ‘greatest blunder’.

It was, as is often the case, a blunder that led to the Nobel-winning discovery. For his PhD thesis, under Robert Kirshner at Harvard, Schmidt mapped type II supernovae (exploding stars that can give off as much light as an entire galaxy) to measure the Hubble Constant – the accepted rate of expansion of the universe. Schmidt initially set out, with Nicholas Suntzeff, Adam Riess and others, to continue this work, expecting if anything to trace a deceleration in the expansion. Their work matched that of Saul Perlmutter’s team. But between them the rival teams found more than 50 supernovae whose light, based on ‘known’ calculations about the Big Bang, was dimmer than expected. With so many supernovae giving this unexpected reading the scientists realised the Universe must have, over the past 5 years, sped up in its expansion, rather than slowing down as expected.

Like Einstein, he admitted: "It seemed too crazy to be right. We were a little scared."

This acceleration is thought to be powered by ‘dark energy’, about which little is known but which is thought to constitute about three quarters of the universe. The Schmidt and Perlmutter teams announced their results in 1998. Having reached the same conclusions independently, the corroborative evidence rocked the world of astrophysics and gave scientists a whole new universe of possibilities to explore.

Brian Schmidt was born in Missoula, Montana, USA in February 1967. When he was 13 the family moved to Anchorage, Alaska, where he attended Bartlett High School, graduating in 1985. The only child of a fisheries biologist he had an early interest in science. As a child he wanted to be a meteorologist but after a summer of volunteering at the National Weather Service he realized it was not for him and set his sights on the stars. Originally, Schmidt regarded astronomy as a hobby, but at the University of Arizona he gained bachelor degrees in physics and astronomy in 1989 before progressing to Harvard for his MA (1992) and PhD the following year.

At Harvard, Schmidt married economics student Jenny Gordon and, after serving as postdoctoral fellow at the Harvard-Smithsonian Center for Astrophysics, the couple moved in 1994 to her homeland of Australia. There Schmidt was granted funds by the Australian National University to help organize the international High-z Supernova Search Team. This team, in addition to Schmidt in Australia, included astronomers in Chile (including co-founder Suntzeff), the United States (including Laureate Riess), and Europe.

Currently leading the SkyMapper telescope project and the associated Southern Sky Survey, Schmidt has received many accolades, including the Australian Malcolm McIntosh Prize and Harvard's Bok Prize in 2000, the Pawsey Medal in 2001, India’s Vainu Bappu Medal in 2002 and he shared the Shaw Prize (2006) and Gruber Cosmology Prize (2007) with Adam Reiss and Saul Perlmutter. In 2008 he was made a fellow of the Australian and United States National Academies, and in 2012 he was made a fellow of the Royal Society. In 2016, Schmidt took up the position as Vice-Chancellor of The Australian National University (ANU).

Schmidt and his family live on a farm near Canberra and own the respected Maipenrai winery, a bottle of which he presented to King Carl XVI Gustaf of Sweden at the Nobel ceremony in Stockholm.

Brian Schmidt's Sketch of Science
Brian Schmidt's Sketch of Science

By Volker Steger

The universe is expanding – ever faster! Brian Schmidt comes in,
fixes his blue eyes on my crayons and starts sketching.
Schmidt is an extrodinary astronomer also in the sense that he uses
starlight not just to observe the universe, but also to grow wine in
his vinyard in Australia. He gave me a bottle – stellar!

Das Universum expandiert – und das immer schneller!
Brian Schmidt kommt herein, fixiert mit seinen blauen Augen
meine Kreiden, und beginnt zu zeichnen.
Schmidt ist ein außergewöhnlicher Astronom, denn er nutzt das
Sternenlicht nicht nur, um das Universium zu beobachten,
sondern auch um seinen eigenen Wein anzubauen.
Eine Flasche brachte er mir mit: Galaktisch!
