Norman Borlaug

Norman Ernest Borlaug was born on 25 March 1914 near Cresco, in Howard County, Iowa, to a family of Norwegian immigrant farmers ^[1]. He grew up on the family homestead in the small community of Saude, where he worked the fields with horses, milked cows, and attended a one room rural school through the eighth grade ^[2]. The physical grind of farm labor before mechanization stayed with him, and he later credited the arrival of tractors and hybrid corn in Iowa during his youth with opening his eyes to what technology could do for agriculture.

His grandfather Nels Borlaug pushed him to continue his education rather than stay on the farm. Borlaug enrolled at the University of Minnesota in 1933, in the depths of the Depression, initially failing the entrance exam and starting in the university's General College before transferring into the forestry program ^[1]. He paid his way through school with odd jobs, and a stint working with the Civilian Conservation Corps brought him into contact with unemployed, hungry men whose condition left a permanent mark on his thinking about food and social stability ^[2].

Borlaug was also a gifted athlete. He wrestled for the University of Minnesota and reached the Big Ten semifinals, and he later said the sport taught him to give everything he had in any contest ^[3]. He was inducted into the National Wrestling Hall of Fame in 1992 for his lifelong support of the sport ^[3].

A lecture by the plant pathologist Elvin C. Stakman on rust, the fungal disease that periodically destroyed North American wheat crops, redirected Borlaug from forestry to plant science. He completed his bachelor's degree in forestry in 1937, then earned a master's degree in 1940 and a doctorate in plant pathology and genetics from the University of Minnesota in 1942 under Stakman's influence ^[1]. During the Second World War he worked as a microbiologist for DuPont in Delaware, where his laboratory handled wartime research projects ^[2].

In 1944 Borlaug joined the Cooperative Wheat Research and Production Program, a joint venture of the Rockefeller Foundation and the Mexican government aimed at raising Mexico's dismal wheat yields ^[4]. The country was then importing much of its grain, and stem rust epidemics had gutted harvests in the early 1940s. Borlaug settled into fieldwork near Mexico City and at an experiment station in the Yaqui Valley of Sonora, in the northwest of the country ^[4].

Conditions were primitive. He often lacked trained staff, machinery, and adequate funding, and he did much of the early crossing and planting with his own hands. Out of necessity he developed the technique known as shuttle breeding, growing two generations of wheat per year by alternating between the high altitude fields near Mexico City and the low, hot Yaqui Valley ^[5]. Colleagues warned that seeds needed a rest period and that the plan wasted money. Instead the method halved breeding time and, as an unplanned bonus, produced wheat that was insensitive to day length and therefore adaptable to a remarkable range of climates around the world ^[5].

Borlaug's team crossed thousands of wheat strains, selecting for resistance to stem rust and for yield. A breakthrough came when the breeders incorporated dwarfing genes from Norin 10, a short strawed Japanese variety, into their rust resistant Mexican lines ^[4]. Traditional tall wheat fell over, or lodged, when heavily fertilized, spilling its grain in the mud. The new semidwarf wheat stood short and stiff, poured its energy into seed rather than stem, and responded to fertilizer and irrigation with yields that stunned agronomists ^[4].

Mexico's transformation came first. By 1956 the country had become self sufficient in wheat, and by the early 1960s its wheat harvest had climbed to several times the level of the 1940s ^[2]. The larger test came in South Asia, where in the mid 1960s drought and population growth had pushed India and Pakistan toward famine. Borlaug and his colleagues shipped tons of semidwarf seed to the subcontinent and worked with local scientists, among them M. S. Swaminathan in India, to get the varieties planted despite bureaucratic resistance and even war between the two countries ^[6]. Wheat harvests in both nations rose sharply within a few seasons, and India went on to become self sufficient in cereals ^[6].

This surge in production across Latin America and Asia became known as the Green Revolution, a phrase coined in 1968 by the American official William Gaud ^[4]. Estimates of the lives affected vary and are difficult to verify precisely, but Borlaug was widely credited with saving hundreds of millions of people from starvation, a claim repeated in the Nobel committee's own materials and in his major obituaries ^[1][7]. In 1970 the Norwegian Nobel Committee awarded him the Nobel Peace Prize, declaring that he had helped provide bread for a hungry world ^[1]. He also served from 1964 as director of the wheat program at the International Maize and Wheat Improvement Center, known by its Spanish acronym CIMMYT, headquartered in Mexico ^[4]. Any list of Norman Borlaug achievements begins with these numbers, yet he insisted the credit belonged to teams of researchers, extension agents, and farmers across many countries.

Borlaug married Margaret Gibson in 1937, while both were students in Minnesota; she had worked to support his studies, and the marriage lasted 69 years until her death in 2007 ^[2]. The couple had a daughter, Jeanie, and a son, William. A third child, Scotty, died in infancy of spina bifida while Borlaug was working in Mexico, a loss he rarely discussed publicly ^[2].

For decades the family's life was shaped by his fieldwork. Borlaug spent long stretches away from home in Sonora and later in Asia, Africa, and the Middle East, a sacrifice he acknowledged with regret in later interviews ^[7]. Those who worked alongside him described a plainspoken, physically tough man who expected researchers to get their hands dirty in the plots rather than direct work from an office.

He remained personally modest despite fame. When the call came from Oslo in October 1970 announcing his Nobel Prize, Borlaug was working in a wheat field outside Mexico City, and by several accounts he initially thought the news was a hoax and went back to work ^[7].

Borlaug never treated the Green Revolution as a finished project. He repeatedly warned that high yield farming had only bought humanity time, perhaps a few decades, and that population growth would erase the gains unless it slowed, a point he made bluntly in his 1970 Nobel lecture ^[1]. From 1984 he taught at Texas A&M University as a distinguished professor of international agriculture, splitting his year between Texas and CIMMYT in Mexico ^[8].

In the 1980s the Japanese philanthropist Ryoichi Sasakawa persuaded Borlaug, then in his seventies, to come out of semiretirement and apply his methods in sub-Saharan Africa. With former U.S. president Jimmy Carter, he led the Sasakawa Global 2000 program, which worked with smallholder farmers in more than a dozen African countries to raise yields of maize, wheat, and other staples ^[8]. Progress there proved harder than in Asia, hampered by poor roads, weak markets, and scarce fertilizer, but Borlaug kept traveling to African field sites into his nineties.

He also became an outspoken defender of modern agricultural science against its critics. He argued that biotechnology and synthetic fertilizer were essential to feeding a growing population on limited land, and that well fed nations had no right to deny such tools to hungry ones ^[7]. In 1986 he founded the World Food Prize, an annual award intended to do for food and agriculture what the Nobel Prizes did for other fields; it is administered from Des Moines, Iowa ^[9]. Borlaug died of lymphoma at his home in Dallas, Texas, on 12 September 2009, at the age of 95 ^[7].

Few scientists have been honored so widely across political lines. Borlaug is one of only a handful of people to receive the Nobel Peace Prize, the U.S. Presidential Medal of Freedom (1977), and the Congressional Gold Medal (2007), and India awarded him the Padma Vibhushan, one of its highest civilian honors ^[8]. In 2014 a statue of Borlaug was placed in the U.S. Capitol's National Statuary Hall as one of Iowa's two representatives, unveiled on the centennial of his birth ^[9].

His scientific legacy runs through the world's wheat fields. Semidwarf varieties descended from his Mexican breeding lines still dominate global wheat production, and the shuttle breeding approach he improvised in the 1940s remains standard practice in international crop research ^[5]. Institutions bearing his name include the Norman Borlaug Institute for International Agriculture at Texas A&M and the Borlaug Global Rust Initiative, launched to fight new rust strains such as Ug99 that he warned about in his final years ^[8].

The Green Revolution also drew serious criticism, and any honest Norman Borlaug biography has to record it. Environmental writers pointed to depleted aquifers, fertilizer runoff, lost crop diversity, and the tendency of the new package of seed and inputs to favor better off farmers ^[6]. Borlaug answered that high yields on existing farmland spared forests and grasslands that would otherwise have gone under the plow, and that the critics had never known hunger. Among the plainest Norman Borlaug facts is this one: a farm boy from Cresco, Iowa, spent his life in wheat plots on four continents and left the world far better fed than he found it ^[1][7].
