Julian Ernst Besag FRS (born March 26, 1945 – died August 6, 2010) was a British scientist. He was a statistician, which means he used math to understand and interpret data. He was best known for his work in spatial statistics. This field helps us understand patterns in things like diseases, images, or even farming. He also worked on Bayesian inference, a way to make smart guesses using math.

Early Life and Education
Julian Besag was born in Loughborough, a town in the UK. He went to Loughborough Grammar School. At first, he started studying engineering at the University of Cambridge. But he soon found his true passion in statistics. He then moved to the University of Birmingham and earned his degree in statistics in 1968.
A Career in Statistics
After finishing his studies, Julian Besag worked as a research assistant at the University of Oxford. He learned a lot from a famous statistician named Maurice Bartlett. Later, he became a teacher at the University of Liverpool.
Inspired by another great statistician, John Tukey, Julian Besag spent a year visiting Princeton in the United States. In 1975, he moved to the University of Durham in the UK. He became a full professor there in 1986.
He also spent time as a visiting professor at the University of Washington in Seattle, USA. After a year at Newcastle University, he returned to Seattle for a longer period. He officially retired in 2007 but continued to be an emeritus professor. This means he still had a connection to the university. When he passed away in 2010, he was also a visiting professor at the Universities of Bath and Bristol in the UK.
Important Discoveries
Julian Besag was a very important researcher. His paper from 1986, called "On the Statistical Analysis of Dirty Pictures," was one of the most referenced papers by a UK math scientist in the 1980s. This shows how much his work helped others.
His contributions were recognized with important awards. The Royal Statistical Society gave him the Guy Medal in Silver in 1983. This was for his amazing work in spatial statistics. In 2004, he was chosen as a Fellow of the Royal Society. This is a very high honor for scientists in the UK.
Understanding Spatial Statistics
One of Julian Besag's most important contributions was in spatial statistics. Imagine you have a grid, like a checkerboard, and each square has some information. Scientists knew that the information in one square could be connected to the information in nearby squares. This is called "stochastic dependence."
Julian Besag wanted to find a way to understand how these squares were connected. He looked at how the information in one square depended on all the other squares around it. He used ideas from physics and other scientists to create a new way to model this.
He shared his new ideas with the Royal Statistical Society in 1974. His work helped scientists better understand patterns in many areas, from how diseases spread to how images are formed.
Later Life and Passing
Julian Besag passed away in Bristol, UK, on August 6, 2010, after having surgery.
