Roy Patrick Kerr is a famous New Zealand mathematician. He is known for discovering the Kerr geometry. This is a special solution to Albert Einstein's equations about general relativity. His discovery helps us understand the strong pull of gravity around huge, spinning objects. It even described rotating black holes before scientists actually found them!

Early Life and Learning
Roy Kerr was born in 1934 in Kurow, New Zealand. He faced challenges early in life. When his father went to war, young Roy lived on a farm. Later, they moved to Christchurch.
School Days and Math Talent
Roy got into St Andrew's College, a private school. His amazing math skills were noticed early. Even without a math teacher there, he was so good he could start university in his third year of math studies in 1951.
University Studies
He studied at Canterbury University College, which was part of the University of New Zealand. He earned his first degree in 1954. In 1955, he went to the University of Cambridge in England. There, he earned his PhD in 1959. His special project was about how things move in general relativity.
Career and Discoveries
After finishing his studies, Roy Kerr worked at Syracuse University in the United States. He also spent some time working for the United States Air Force.
Important Work in Texas
In 1962, Kerr joined a group of scientists at the University of Texas at Austin. This group studied relativity. In 1963, scientists were trying to understand quasars. These are very bright objects far away in space.
Solving Einstein's Equations
At a big meeting in Dallas in 1963, Kerr shared his amazing discovery. He presented his solution to Einstein's equations. This solution described how gravity works around spinning black holes. Another famous scientist, Subrahmanyan Chandrasekhar, said that finding this solution was the most "shattering experience" in his scientific life. He meant it was incredibly important!
Developing New Concepts
In 1965, Roy Kerr worked with Alfred Schild. They came up with ideas like Kerr–Schild perturbations. They also developed the Kerr–Newman metric, which describes charged, spinning black holes.
Return to New Zealand
In 1971, Kerr went back to New Zealand. He became a Professor of Mathematics at the University of Canterbury. He worked there for 22 years. For 10 of those years, he was the head of the math department. He retired in 1993.
Awards and Recognitions
Roy Kerr has received many important awards for his work. These awards show how much his discoveries have helped us understand the universe.
- Hector Medal (1982): For his work in theoretical physics, especially his solution to Einstein's equations.
- Hughes Medal (1984): For his important work on relativity and discovering the "Kerr Black Hole."
- Rutherford Medal (1993): For his amazing discoveries about black holes.
- Albert Einstein Medal (2013): This is a very special award from Switzerland. He was the first New Zealander to receive it.
- Crafoord Prize in Astronomy (2016): Another major award for his contributions to astronomy.
- Oskar Klein Medal (2020): An award from Sweden for his work in theoretical physics.
In 2011, he was also made a Companion of the New Zealand Order of Merit. This was for his great service to astrophysics. In 2015, the University of Canterbury gave him an honorary Doctor of Science degree.
Personal Life
Roy Kerr is married to Margaret. They lived in Tauranga for nine years. In 2022, they moved back to Christchurch, where they live now. Roy Kerr is also a very good bridge player. He even played for New Zealand in the 1970s. He helped create a special way of playing bridge called the Symmetric Relay System.
