Remembering Dr Peter Nixon: Geologist, Mentor, Pioneer
The Overberg Geoscientists Group shares the sad news of the passing of Dr Peter Nixon, a respected geologist and beloved friend to many in the field.
Peter was a leader in the study of mantle xenoliths and kimberlites, known not just for his research, but for the way he inspired and supported those around him. His journey began in 1957 when, fresh from the African Institute of Earth Sciences, he camped at the Letseng-la-Terae kimberlite in Lesotho - helping lay the groundwork for what would become one of the most valuable diamond mines in the world.
Peter earned his PhD at Leeds, then worked as Principal Geologist in Uganda, and later as Mining Geologist and Acting Commissioner of Mines in Lesotho. His work attracted international geologists and helped shape the mining industry in the region. His time in Africa, alongside his wife Mary, was also known for the warmth and hospitality they shared with visiting geoscientists.
He went on to serve as a Professor at Leeds and Director of the Institute of African Geosciences, bringing with him not just academic excellence, but a deep understanding of people and places. His adventures even included work in Papua New Guinea, where his curiosity and ability to connect with people led to extraordinary discoveries.
Peter was known for his deep knowledge, open mind, and humble nature. More than a scientist, he was a mentor, husband, father, and grandfather. He will be greatly missed.
Our thoughts are with Mary, Jacky, Sally, Kathy, Penny, and the extended family. A full biography will be published in due course.
