Some context: Norman Ernest Borlaug (March 25, 1914 - September 12, 2009) was an American agronomist and humanitarian who led initiatives worldwide that contributed to the extensive increases in agricultural production termed the Green Revolution. Borlaug was awarded multiple honors for his work, including the Nobel Peace Prize, the Presidential Medal of Freedom and the Congressional Gold Medal. Borlaug received his B.Sc. in Forestry in 1937 and Ph.D. in plant pathology and genetics from the University of Minnesota in 1942.
Borlaug's name is nearly synonymous with the Green Revolution, against which many criticisms have been mounted over the decades by environmentalists and some nutritionalists. Throughout his years of research, Borlaug's programs often faced opposition by people who consider genetic crossbreeding to be unnatural or to have negative effects. Borlaug's work has been criticized for bringing large-scale monoculture, input-intensive farming techniques to countries that had previously relied on subsistence farming. These farming techniques often reap large profits for U.S. agribusiness and agrochemical corporations and have been criticized for widening social inequality in the countries owing to uneven food distribution while forcing a capitalist agenda of U.S. corporations onto countries that had undergone land reform.  Other concerns of his critics and critics of biotechnology in general include: that the construction of roads in populated third-world areas could lead to the destruction of wilderness; the crossing of genetic barriers; the inability of crops to fulfill all nutritional requirements; the decreased biodiversity from planting a small number of varieties; the environmental and economic effects of inorganic fertilizer and pesticides; the amount of herbicide sprayed on fields of herbicide-resistant crops.  Borlaug dismissed most claims of critics, but did take certain concerns seriously. He stated that his work has been "a change in the right direction, but it has not transformed the world into a Utopia". Of environmental lobbyists he stated, "some of the environmental lobbyists of the Western nations are the salt of the earth, but many of them are elitists. They've never experienced the physical sensation of hunger. They do their lobbying from comfortable office suites in Washington or Brussels. If they lived just one month amid the misery of the developing world, as I have for fifty years, they'd be crying out for tractors and fertilizer and irrigation canals and be outraged that fashionable elitists back home were trying to deny them these things".

Some context: O'Neill was born in a hotel, the Barrett House, at Broadway and 43rd Street, on what was then Longacre Square (now Times Square). A commemorative plaque was first dedicated there in 1957. The site is now occupied by 1500 Broadway, which houses offices, retail, and ABC Studios. He was the son of Irish immigrant actor James O'Neill and Mary Ellen Quinlan, who was also of Irish descent.
After suffering from multiple health problems (including depression and alcoholism) over many years, O'Neill ultimately faced a severe Parkinsons-like tremor in his hands which made it impossible for him to write during the last 10 years of his life; he had tried using dictation but found himself unable to compose in that way. While at Tao House, O'Neill had intended to write a cycle of 11 plays chronicling an American family since the 1800s. Only two of these, A Touch of the Poet and More Stately Mansions, were ever completed. As his health worsened, O'Neill lost inspiration for the project and wrote three largely autobiographical plays, The Iceman Cometh, Long Day's Journey into Night, and A Moon for the Misbegotten. He managed to complete Moon for the Misbegotten in 1943, just before leaving Tao House and losing his ability to write. Drafts of many other uncompleted plays were destroyed by Carlotta at Eugene's request.  O'Neill died in Room 401 of the Sheraton Hotel (now Boston University's Shelton Hall) on Bay State Road in Boston, on November 27, 1953, at the age of 65. As he was dying, he whispered his last words: "I knew it. I knew it. Born in a hotel room and died in a hotel room." Dr. Harry Kozol, the lead prosecuting expert of the Patty Hearst trial, treated O'Neill during these last years of illness. He also was present for O'Neill's death and announced the fact to the public.  O'Neill is interred in the Forest Hills Cemetery in Boston's Jamaica Plain neighborhood.  In 1956 Carlotta arranged for his autobiographical play Long Day's Journey into Night to be published, although his written instructions had stipulated that it not be made public until 25 years after his death. It was produced on stage to tremendous critical acclaim and won the Pulitzer Prize in 1957. This last play is widely considered to be his finest. Other posthumously-published works include A Touch of the Poet (1958) and More Stately Mansions (1967).  The United States Postal Service honored O'Neill with a Prominent Americans series (1965-1978) $1 postage stamp.
