John Rodney Guest facts for kids
John Rodney Guest is a famous British scientist who studies tiny living things called microbes. He is known as a molecular microbiologist. This means he looks at how these tiny organisms work at a very small, molecular level. He was born on December 27, 1935.

Who is John Rodney Guest?
John Rodney Guest was born in Leeds, West Yorkshire. His father was Sidney Ramsey Guest. John went to the University of Leeds and earned his first degree in 1957. Later, he continued his studies at Trinity College, Oxford, where he received his Ph.D. in 1961.
His Scientific Journey
After finishing his studies, John Rodney Guest worked as a Fellow at Oxford University from 1960 to 1965. He also spent time in the United States as a Fulbright Scholar at Stanford University in 1963–64.
In 1965, he became a Lecturer in Microbiology at the University of Sheffield. He continued to teach and research there, becoming a Senior Lecturer and Reader. Since 1981, he has been a Professor of Microbiology at Sheffield.
Discovering How Bacteria Work
Professor Guest is famous for his research on bacteria. He used special methods to understand how bacteria grow and get energy. He studied their genes and how they use different chemical processes.
He focused on important pathways inside bacteria. These include how they build up molecules (anabolic pathways) and how they break them down for energy (catabolic pathways). He especially studied the citric acid cycle, which is a key process for energy in many living things. He looked at how bacteria use this cycle both with and without oxygen.
Awards and Family Life
In 1986, John Rodney Guest was chosen to be a Fellow of the Royal Society. This is a very high honor for scientists in the United Kingdom. In 1995, he gave the famous Leeuwenhoek Lecture. His talk was about how life can exist without oxygen, which is a fascinating topic in microbiology.
John Rodney Guest married Barbara Dearsley in 1962. They have three children: a son named Chris (born in 1968) and two daughters named Sue (born in 1963) and Julia (born in 1965).
