He was born in Belfast on June 26, 1824. People later knew him as Lord Kelvin. He was a mathematician, a physicist, and an engineer. He spent 53 years as a professor at the University of Glasgow.

This school was his home for most of his career. He even became its Chancellor in 1904.

Kelvin did amazing work with the study of heat, called thermodynamics.

He wanted to find a way to measure heat that did not depend on specific materials. He proposed an absolute temperature scale. This scale leads to a point called absolute zero. This is the coldest possible temperature. Kelvin found its true value was about -273.15 degrees Celsius.

Today, we use the kelvin unit to measure temperature in his honor.

His journey into science began very early in his life.

His father, James Thomson, was a teacher of math and engineering. William started studying at the University of Glasgow when he was only 10 years old. By age 12, he won a prize for translating Ancient Greek. At age 22, he became a professor at Glasgow. This was a very big job for someone so young. He used math to help explain how electricity and heat work together.

Kelvin was also a very talented engineer.

He worked on the transatlantic telegraph project to send messages across the ocean. Because of this, Queen Victoria knighted him in 1866. He also helped make the mariner's compass more reliable for sailors.

This helped people travel safely on the sea. In 1892, he was even made a Baron in the House of Lords. He received the Copley Medal in 1883 for his great work.

Many of his big ideas connect to things we use every day. His work on electricity helps us understand how modern machines run. His work on heat helps us understand how engines and weather work.

He even worked with the company Kodak as a vice-chairman. Kelvin lived in a large house called Netherhall in Largs. He died there in 1907. His many discoveries still help scientists study the physical world today.
