Richard Guy was a mathematician who saw the world through numbers and patterns. He was interested in many different areas of math. He studied number theory, which looks at how numbers work. He also studied geometry, which is the study of shapes. He loved recreational mathematics, which means math used for fun and games. He even studied graph theory and combinatorics. He believed that math could be found in many places. Even his ideas about small numbers were very famous.

Richard found joy in solving puzzles and creating new ones. He was very interested in problems that no one had solved yet. He wrote two important books about these unsolved puzzles. One was called Unsolved Problems in Number Theory. The other was Unsolved Problems in Combinatorial Games. These books helped many new mathematicians start their own work. He also studied a special game called the Game of Life. In 1970, he discovered a moving part in that game called a glider.

His journey in math began when he was a young student in England. He went to Gonville and Caius College in Cambridge. While he was there, he loved to create chess problems. He even helped invent a special code for chess called the GBR code. This code helps people organize different ways chess pieces move. He later met a famous mathematician named Paul Erdős in Singapore. Working with Erdős gave him the confidence to be a researcher. They even wrote four papers together.

Richard lived a very long and busy life. He was born in Nuneaton, England, in 1916. He taught in many different places like London, Singapore, and India. Later, he moved to Canada to teach at the University of Calgary. He wrote more than 300 scholarly articles during his career. He also wrote more than a dozen books with other experts. Even after he officially retired in 1982, he kept working. He went to his office five days a week even after he turned 100.

Math was his first love, but he had other passions too. He loved mountain climbing and being in the snow. He traveled to places like Iceland and the Himalayas to climb. He married his wife, Louise, in 1940, and they shared these loves. They even helped people learn to lead in the mountains. In 2014, he gave $100,000 to the Alpine Club of Canada. A small hut was even named after him and Louise. Richard Guy died in 2020 at the age of 103.
