To mark the occasion of 20 years after his retirement, former maize germplasm bank assistant, Guadalupe Guevara, was paid a visit on 24 January 2008 by Suketoshi Taba, head of maize genetic resources, Mauro Ramírez, head of maize seed shipments, and consultant Garrison Wilkes. Prior to his retirement, Don Lupe, as he was known, had worked for more than 37 years in international agricultural research initiatives predating the Office of Special studies, and counted among his colleagues some well-known researchers from CIMMYT’s history, including Ed Wellhausen and Mario Gutiérrez. He was very pleased to see the group of old friends, who found him in excellent spirits and health. All the best, Don Lupe!
