He was the scientific director of the Utrecht University Botanic Gardens and worked as a researcher at the Station for Nursery Stock at Boskoop. He is considered one of the world authorities on Acer, the maples.
Piet de Jong was born in Bent, a hamlet halfway between Hazerswoude and Zoeterwoude. He was a farmer's son, the oldest in a family of six children. When he was seven, he started growing plants. He visited the primary school at Hazerswoude. After that he went to the gymnasiuminLeiden.[1]
1960 he started his studies at Wageningen University and Research Centre - which was called 'Landbouwhogeschool' (Agricultural College) in those days. He got a degree in horticultural plant breeding, with optional courses in (botanical) systematics and phytogeography, plant anatomy and virology. Afterwards, he did biosystematic research on Acer in the Laboratory of botanical systematics and phytogeography.[2] He had been involved in research on the flowering of maples before he got his degree.[1] The maples have always been his great passion.
In 1971 he became researcher at the Institute for Horticultural Plant Breeding (Instituut voor de Veredeling van Tuinbouwgewassen - IVT) in Wageningen. He worked on taxonomic problems in plant breeding research and biosystematic research of lilies.[2]
From 1988 to 1997, Piet de Jong was in charge of the practical research on tree growing at the 'Proefstation voor de Boomkwekerij' (Trial station for tree nursery) in Boskoop.[3]
After his retirement De Jong is still actively involved with the Von Gimborn Arboretum.[4]
