When Monkombu Sambasivan Swaminathan received the first World Food Prize in 1987, he shared with the world a mantra his father had given him long ago: “The word impossible exists mainly in our minds.” He has lived those words in his own life, in ways big and small. In the 1960s and 1970s, when he spearheaded the introduction of high-yielding wheat and rice varieties to Indian farmers, the Green Revolution, it was a near-impossible task, grandiose and historic. Today, when the nonagenarian—he has just turned 95—goes to office, the M S Swaminathan Research Foundation in Chennai, every day—one wonders if he still recalls his father’s words.
