Ingo Potrykus

Ingo Potrykus (born 5 December 1933) is Professor Emeritus of Plant Sciences at the Institute of Plant Sciences of the Swiss Federal Institute of Technology (ETH), Zurich from which he retired in 1999. His research group applied gene technology to contribute to food security in developing countries. Together with Peter Beyer, he is one of the co-inventors of golden rice. In 2014 he was chairman of the Golden Rice Humanitarian Board.

Background
Potrykus was born on 5 December 1933 in Germany. He studied biology at the University of Cologne and earned his doctorate at the Max-Planck Institute for Plant Breeding Research, Cologne, Germany. After several years at the Institute of Plant Physiology, University of Hohenheim, he became research group leader at the Max-Planck Institute for Plant Genetics. Ladenburg, Germany. In 1976 he transferred to Basel, Switzerland to establish the area of plant genetic engineering at the Friedrich Miescher Institute. In 1986 he became professor of plant sciences at the Swiss Federal Institute of Technology, concentrating on the Biotechnology of Plants. He retired from this institute in 1999 at the age of 65.

Research
Motivated by the upcoming food crisis problem of malnutrition in developing countries and the potential of gene technology to contribute to food security, Potrykus and his research group dedicated their work to genetic engineering projects aimed at improving yield stability and food quality of crops such as rice, wheat, millet, sorghum, and cassava. The most significant development so far has been the creation of golden rice, a new rice variety providing vitamin A. This strain of rice is widely seen as the model example of how to sustainably reduce malnutrition in developing countries. Potrykus began thinking about using genetic engineering to improve the nutritional qualities of rice in the late 1980s. He knew that of some 3 billion people who depend on rice as their staple crop, around 10% risk some level of vitamin A deficiency. This problem interested Potrykus for numerous reasons, including the scientific challenge of transferring not just a single gene, but a group of genes that represented a key part of a biochemical pathway. In 1993, with funding from the Rockefeller Foundation, Potrykus teamed up with Peter Beyer and they launched what would become a seven-year, $2.6 million project to develop Golden Rice.

Since his retirement in 1999, Ingo Potrykus - as president of the International Humanitarian Golden Rice Board - has devoted his energy to guiding Golden Rice towards subsistence farmers across the many hurdles of a GMO-crop. To this end he has been established collaboration with 14 rice institutions in India, China, Vietnam, Bangladesh, Indonesia, and Philippines. In 2013 Potrykus met the Pope who offered his personal blessing to Golden Rice although the Pope was concerned that genetic modification benefited big business rather than the poor.

Personal life
Potrykus has been married since 1960 to Inge Heilingbrunner. He has three children and eight grandchildren.
