Condé Nast Portfolio described him as "one of the most generous but low-key philanthropists in America". Koch has contributed to several charities including Lincoln Center, Sloan Kettering, New York-Presbyterian Hospital and the Dinosaur Wing at the American Museum of Natural History. The New York State Theater at Lincoln Center, home of the New York City Ballet, was renamed the David H. Koch Theater in 2008 following a gift of $100 million for the renovation of the theater. Koch was the fourth richest person in the US as of 2012, and the wealthiest resident of New York City as of 2013.
As of June 2018, he was ranked as the 11th-richest person in the world, with an estimated net worth of $51 billion.
Early life and education
Koch was born in Wichita, Kansas, the son of Mary Clementine (née Robinson) and Fred Chase Koch, a chemical engineer. David's paternal grandfather, Harry Koch, was a Dutch immigrant who founded the Quanah Tribune-Chief newspaper and was a founding shareholder of Quanah, Acme and Pacific Railway. David is the third of four sons, with elder brothers Frederick R. Koch, Charles Koch, and nineteen-minute younger twin Bill Koch. Among his maternal great-great-grandparents were William Ingraham Kip, an Episcopalian bishop, William Burnet Kinney, a politician, and Elizabeth Clementine Stedman, a writer.
Koch attended the Deerfield Academy prep school in Massachusetts, graduating in 1959. He went on to the Massachusetts Institute of Technology (MIT), earning both a bachelor's (1962) and a master's degree (1963) in chemical engineering. He is a member of the Beta Theta Pi Fraternity. Koch played basketball at MIT, averaging 21 points per game at MIT over three years, a school record. He also held the single-game scoring record of 41 points from 1962 until 2009, when it was eclipsed by Jimmy Bartolotta.
Career at Koch Industries
In 1970, Koch joined Koch Industries under his brother Charles, to work as a technical-services manager. He founded the company's New York office and in 1979 he became the president of his own division, Koch Engineering, renamed Chemical Technology Group. In 1985, Koch Industries was sued by Bill Koch and Frederick R. Koch for the first time in a long series of lawsuits about ownership, that lasted until 2001. As of 2010, David Koch owned 42 percent of Koch Industries, as does his brother Charles. He holds 4 U.S patents.
On June 5, 2018, the company announced his retirement from the company due to declining health issues.
Koch was the Libertarian Party's vice-presidential candidate in the 1980 presidential election, sharing the party ticket with presidential candidate Ed Clark. The Clark–Koch ticket promised to abolish Social Security, the Federal Reserve Board, welfare, minimum-wage laws, corporate taxes, all price supports and subsidies for agriculture and business, and U.S. Federal agencies including the SEC, EPA, ICC, FTC, OSHA, FBI, CIA, and DOE. The ticket received 921,128 votes, 1% of the total nationwide vote, the Libertarian Party national ticket's best showing until 2016 in terms of percentage and its best showing in terms of raw votes until the 2012 presidential election, although that number was surpassed again in 2016. "Compared to what [the Libertarians had] gotten before," Charles said, "and where we were as a movement or as a political/ideological point of view, that was pretty remarkable, to get 1 percent of the vote."
Koch credits the campaign of Roger MacBride as his inspiration for getting involved in politics:
Here was a great guy, advocating all the things I believed in. He wanted less government and taxes, and was talking about repealing all these victimless crime laws that accumulated on the books. I have friends who smoke pot. I know many homosexuals. It's ridiculous to treat them as criminals—and here was someone running for president, saying just that.
Koch gave his own Vice Presidential campaign $100,000 a month after being chosen as Ed Clark's running mate. "We'd like to abolish the Federal Elections Commission and all the limits on campaign spending anyway," Koch said in 1980. When asked why he ran, he replied: "Lord knows I didn't need a job, but I believe in what the Libertarians are saying. I suppose if they hadn't come along, I could have been a big Republican from Wichita. But hell—everybody from Kansas is a Republican."
Koch considers himself a social liberal, supporting women's right to choose, gay rights, same-sex marriage and stem-cell research. He opposes the war on drugs. Koch supports policies that promote individual liberty and free market principles, and supports reduced government spending. Koch supports a non-interventionist foreign policy; "Pursuing a very aggressive foreign policy," he says, "is an extremely expensive endeavor for the U.S. government. The cost of maintaining a huge military force abroad is gigantic. It's so big it puts a severe strain on the U.S. economy, creating economic hardships here at home." Koch opposed the Iraq War, saying that the war has "cost a lot of money and it's taken so many American lives", and "I question whether that was the right thing to do. In hindsight that looks like it was not a good policy". In an impromptu interview with the blog ThinkProgress, he was quoted as saying he would like the new Republican Congress to "cut the hell out of spending, balance the budget, reduce regulations, and support business." He is against the Patient Protection and Affordable Care Act and the Dodd–Frank Wall Street Reform and Consumer Protection Act. He is skeptical about anthropogenic global warming. He has said a warmer planet would be good because "Earth will be able to support enormously more people because a far greater land area will be available to produce food".
Koch has many thoughts on several of President Obama's policies. An article from the Weekly Standard, detailing the "left's obsession" with the Koch brothers, quotes Koch stating that Obama is "the most radical president we've ever had as a nation ... and has done more damage to the free enterprise system and long-term prosperity than any president we've ever had." Koch said that Obama's father's economic socialism, practiced in Kenya, explains why Obama has "sort of antibusiness and anti-free enterprise" influences. Koch said that Obama is "scary", a "hardcore socialist" who is "marvelous at pretending to be something other than that." Koch contributed to both Republicans and Democrats in 2012, with the majority of his contributions going to Republican candidates.
In 1984, Koch founded, served as Chairman of the board of directors of, and donated to the free-market Citizens for a Sound Economy (CSE). Richard H. Fink served as its first president. Koch is Chairman of the Board and gave initial funding to the Americans for Prosperity Foundation and to a related advocacy organization, Americans for Prosperity. A Koch Industries spokesperson issued a press release stating "No funding has been provided by Koch companies, the Koch foundations, or Charles Koch or David Koch specifically to support the tea parties." Koch was the top initial funder of the Americans for Prosperity Foundation at $850,000. Koch said that he sympathizes with the Tea Party movement, but denies directly supporting it, stating: "I've never been to a tea party event. No one representing the tea party has ever even approached me."
In February 2012, during the Wisconsin gubernatorial recall election, Koch said of Wisconsin governor Scott Walker, "We're helping him, as we should. We've gotten pretty good at this over the years. We've spent a lot of money in Wisconsin. We're going to spend more," and said that by "we" he meant Americans for Prosperity.
Koch established the David H. Koch Charitable Foundation. Since 2006, the Chronicle of Philanthropy has listed Koch as one of the world's top 50 philanthropists. He has sat on the Board of Trustees of New York-Presbyterian Hospital since 1988.
Koch says that his biggest contributions go toward a "moon shot" campaign to finding the cure for cancer, according to his profile on Forbes. Between 1998 and 2012, Koch contributed at least $395 million to medical research causes and institutions.
Koch sits on the Board of Directors of the Prostate Cancer Foundation and has contributed $41 million to the foundation, including $5 million to a collaborative project in the field of nanotechnology. Koch is the eponym of the David H. Koch Chair of the Prostate Cancer Foundation, a position currently held by Dr. Jonathan Simons.
In 2007, he contributed $100 million to the Massachusetts Institute of Technology for the construction of a new 350,000-square-foot (33,000 m2) research and technology facility to serve as the home of the David H. Koch Institute for Integrative Cancer Research, Since joining the MIT Corporation in 1988, Koch has given a total of $185 million to MIT. $15 million to New York-Presbyterian Hospital Weill Cornell Medical Center and $30 million to the Memorial Sloan–Kettering Cancer Center in New York.
In 2011 Koch gave $5 million to the House Ear Institute, in Los Angeles, to create a center for hearing restoration, and $25 million to the Hospital for Special Surgery in New York City In 2013, he gave $100 million to NewYork–Presbyterian Hospital, the largest philanthropic donation in its history, beginning a $2 billion campaign to conclude in 2019 for a new ambulatory care center and renovation the infrastructure of the hospital's five sites.
In 2015, he committed $150 million to Memorial Sloan Kettering Cancer Center in New York to build the David H. Koch Center for Cancer Care, which will be housed in a 23-story building in development between East 73rd and 74th Streets overlooking the FDR Drive. The center will combine state-of-the-art cancer treatment in an environment that supports patients, families, and caregivers. The building will include flexible personal and community spaces, educational offerings, and opportunities for physical exercise.
In July 2008, Koch pledged $100 million over 10 years to renovate the New York State Theater in the Lincoln Center for the Performing Arts, now named in his honor  and pledged $10 million to renovate fountains outside the Metropolitan Museum of Art.
Koch has been a trustee of the American Ballet Theatre for 25 years and has contributed more than $6 million to the theater. He also sits on the Board of Trustees of WGBH-TV, which produces more than two-thirds of the nationally distributed programs broadcast by PBS.
From 1982 to 2013, Koch contributed $18.6 million to WGBH Educational Foundation, including $10 million to the Public Broadcasting Service (PBS) show Nova. Koch is a contributor to the Smithsonian Institution in Washington, D.C., including a $20 million gift to the American Museum of Natural History, creating the David H. Koch Dinosaur Wing and a contribution of $15 million to the National Museum of Natural History to create the new David H. Koch Hall of Human Origins, which opened on the museum's 100th anniversary of its location on the National Mall on March 17, 2010. He also serves on the executive board of the Institute of Human Origins. In 2012, Koch contributed US$35 million to the Smithsonian to build a new dinosaur exhibition hall at the National Museum of Natural History.
Koch also financed the construction of the $68 million Koch Center for mathematics, science and technology at the Deerfield Academy, a highly selective independent, coeducational boarding school at Deerfield, Massachusetts,[non-primary source needed] and was named its first and only Lifetime Trustee.
Koch gave $10 million to the Cold Spring Harbor Laboratory  where he was honored with the Double Helix Medal for Corporate Leadership for supporting research that, "improves the health of people everywhere".[non-primary source needed]
In July 2015 David Koch and his brother were commended by both President Obama and activist Anthony Van Jones for their bipartisan efforts to reform the prison system in the United States. For nearly ten years the Kochs have been advocating for several reforms within the criminal justice system which include reducing recidivism rates, simplifying the employment process for the rehabilitated, and defending private property from government seizures through asset forfeiture. Allying with groups such as the ACLU, the Center for American Progress, Families Against Mandatory Minimums, the Coalition for Public Safety, and the MacArthur Foundation, the Kochs maintain the current prison system unfairly targets low-income and minority communities at the expense of the public budget.
Criticism and recognition
In August 2010, Jane Mayer wrote an article in The New Yorker on the political spending of David and Charles Koch stating: "As their fortunes grew, Charles and David Koch became the primary underwriters of hard-line libertarian politics in America." Mayer's article was criticized by conservatives for not enumerating the Kochs' charitable donations. Mayer's article was also criticized by Koch Industries as using "psycho-biographic innuendo, unnamed sources, and half-truths".
An opinion piece by journalist Yasha Levine in the New York Observer said Mayer's article failed to mention that the Kochs' "free market philanthropy belies the immense profit they have made from corporate welfare".
Kimberly O. Dennis, president and chief executive officer of the Searle Freedom Trust, said in 2010 that the Kochs are acting against their economic interest in promoting "getting government out of the business of running the economy. If they were truly interested in protecting their profits, they wouldn't be spending so much to shrink government; they'd be looking for a bigger slice of the pie for themselves. Their funding is devoted to promoting free-market capitalism, not crony capitalism."[non-primary source needed]
In 1992, Koch was diagnosed with prostate cancer. He underwent radiation, surgery, and hormone therapy, but the cancer has returned every time. Koch has said he believes his experience with cancer has encouraged him to fund medical research.
