# Laurance Rockefeller
**Laurance Spelman Rockefeller** (May 26, 1910 – July 11, 2004) was an American financier, venture capital pioneer, and conservationist, the fourth child and third son of John D. and [Abby Aldrich Rockefeller](https://www.edgepedia.org/abby-aldrich-rockefeller), who financed aviation and aerospace start-ups from the 1930s onward and gave land and money that helped create or expand several United States national parks.[1](https://www.nps.gov/articles/000/legacy-of-laurance.htm) • [2](https://www.nytimes.com/2004/07/12/business/laurance-s-rockefeller-passionate-conservationist-and-investor-is-dead-at-94.html) • [20](https://baike.baidu.com/en/item/Laurence%20Rockefeller/3420871) Forbes called him "The Father Of Venture Capital"[3](https://www.forbes.com/forbes/2000/0403/6508074s1.html).

## Early investing career: aviation bets of the 1930s
Laurance Rockefeller began making venture-style investments during the [Great Depression](https://www.edgepedia.org/great-depression), before modern institutional venture capital had emerged; wealthy families were the main source of risk capital for private companies[4](https://kenney.faculty.ucdavis.edu/wp-content/uploads/sites/332/2018/03/how-venture-capital-became-a-component-of.pdf) • [12](https://ventureforward.org/resources-for-emerging-vc/vc-history/). One of his first investments was participating in the 1938 refinancing of Captain Eddie Rickenbacker's Eastern Air Lines[4](https://kenney.faculty.ucdavis.edu/wp-content/uploads/sites/332/2018/03/how-venture-capital-became-a-component-of.pdf). A 1959 Time profile says he helped round up $3,500,000 for the refinancing and took 24,400 shares at $9 each; by 1959, at $155 pre-split, his $3,782,000 stake made him Eastern's biggest stockholder[6](https://time.com/archive/6802473/business-space-age-risk-capitalist/). Britannica records that within a few years he held the largest share of the company's stock, 100 percent of its preferred[13](https://www.britannica.com/money/Laurance-S-Rockefeller).
His second signature bet was aircraft. In 1938 J. S. McDonnell Jr., an airplane designer at the Glenn L. Martin Aircraft Company, launched a new firm in St. Louis supported by Laurance Rockefeller[4](https://kenney.faculty.ucdavis.edu/wp-content/uploads/sites/332/2018/03/how-venture-capital-became-a-component-of.pdf). The two Time profiles give different figures for his initial outlay: $10,000 in 1939 in the 1959 profile[6](https://time.com/archive/6802473/business-space-age-risk-capitalist/), and $40,000 in cash for 4,000 shares of highly speculative preferred stock in the 1954 profile, which adds that he and his brothers later raised their stake to $400,000 and a one-fifth voting interest[14](https://time.com/archive/6785457/investment-rock-bros-inc/). Forbes later reported that he accumulated 27 percent of McDonnell Aircraft, maker of the F-4 Phantom fighter[3](https://www.forbes.com/forbes/2000/0403/6508074s1.html).
The niche was deliberate. By 1940 he had invested almost $100,000 of his own money in small aeronautics companies, and Assistant Secretary of the Navy James Forrestal asked him to organize a company to help finance firms of interest to the Navy Department; during World War II he served as a Navy procurement officer[4](https://kenney.faculty.ucdavis.edu/wp-content/uploads/sites/332/2018/03/how-venture-capital-became-a-component-of.pdf) • [13](https://www.britannica.com/money/Laurance-S-Rockefeller). Aviation firms supplying the military proved a lucrative investment niche[4](https://kenney.faculty.ucdavis.edu/wp-content/uploads/sites/332/2018/03/how-venture-capital-became-a-component-of.pdf).
## Rockefeller Brothers, Inc. and Venrock
In January 1946 Laurance and his siblings, with Ted Walkowicz and Harper Woodward, formed Rockefeller Brothers Incorporated to manage the [Rockefeller family](https://www.edgepedia.org/rockefeller-family)'s venture capital investments, starting with $1.5 million of capital and operating roughly 20 years, from 1946 to 1966[5](https://dimes.rockarch.org/collections/6q672ZfPBCNHN7HjZBWsYA?category=). Laurance became its president[15](https://www.encyclopedia.com/humanities/encyclopedias-almanacs-transcripts-and-maps/rockefeller-laurance-spelman). A 1954 Time account described it as a research and investment house interested only in enterprises offering genuine risk, planning to take money out of well-established companies to fund new speculative ventures; since 1946 it had put $7,000,000 into [Nelson Rockefeller](https://www.edgepedia.org/nelson-rockefeller)'s International Basic Economy Corp., which started new Latin American businesses with local capital[14](https://time.com/archive/6785457/investment-rock-bros-inc/). RBI's sectors were aviation, aerospace, communications, computing and data processing, electronics, energy, lasers, optics, and physics[5](https://dimes.rockarch.org/collections/6q672ZfPBCNHN7HjZBWsYA?category=).
Family capital, not a raised fund, is the structural difference from modern venture capital: RBI invested the Rockefellers' own money at a time when, as the industry history notes, wealthy families such as the Vanderbilts, Rockefellers, and Whitneys were the main source of risk capital, and the first modern VC firm, [American Research and Development Corporation](https://www.edgepedia.org/american-research-and-development-corporation), was formed only in 1946 by [Karl Compton](https://www.edgepedia.org/karl-compton), Merrill Griswold, Ralph Flanders, and Georges F. Doriot[12](https://ventureforward.org/resources-for-emerging-vc/vc-history/). Industry histories trace the VC industry's roots to that same year through the formation of J.H. Whitney and Rockefeller Brothers, Inc.[12](https://ventureforward.org/resources-for-emerging-vc/vc-history/).
In 1969 the family's investments were consolidated into Venrock, which continued funding entrepreneurs in science and technology; beginning in August 1969 Laurance's venture investments in aviation, aerospace, electronics, lasers, data processing, and nuclear power ran through it[5](https://dimes.rockarch.org/collections/6q672ZfPBCNHN7HjZBWsYA?category=) • [10](https://rockarch.org/resources/about-the-rockefellers/laurance-s-rockefeller/). Venrock provided early funding for Intel and Apple Computer[16](https://catalogimages.wiley.com/images/db/pdf/9781118551981.excerpt.pdf) • [2](https://www.nytimes.com/2004/07/12/business/laurance-s-rockefeller-passionate-conservationist-and-investor-is-dead-at-94.html).
## By the numbers
The 1959 Time profile gives deal-level figures for his personal portfolio. Since World War II he had put roughly $5,000,000 into some two dozen long-shot companies, and the value of his stocks in those companies was then $33 million, against a personal worth of about $200 million[6](https://time.com/archive/6802473/business-space-age-risk-capitalist/). Individual outcomes:
- **Eastern Air Lines**: 24,400 shares bought at $9, worth $155 each pre-split in 1959[6](https://time.com/archive/6802473/business-space-age-risk-capitalist/).
- **McDonnell Aircraft**: $10,000 in 1939; he sold out when his holdings were worth $400,000, as he usually did when a company matured[6](https://time.com/archive/6802473/business-space-age-risk-capitalist/).
- **Reaction Motors**: $500,000 after World War II; after the firm merged with Thiokol Chemical Corp., his Thiokol stock was worth $4,200,000[6](https://time.com/archive/6802473/business-space-age-risk-capitalist/). (The 1959 article says the merger was "last year," implying 1958; another Time source dates it to 1968.)
- **Marquardt Aircraft**: $202,000 in 1950 into the ramjet pioneer; his interest grew to $5,200,000 after Marquardt made ramjets for the Bomarc missile[6](https://time.com/archive/6802473/business-space-age-risk-capitalist/).
- **Itek**: $279,000 about two years before 1959, in shares that ranged from $2 to as high as $315, with a paper profit above $10 million[6](https://time.com/archive/6802473/business-space-age-risk-capitalist/).
Across the whole program, a financial-history study counts 59 Rockefeller investments between 1938 and 1969 achieving an investment multiple of 3.2, while the stock market over the same period produced a multiple of 8.6[7](https://finhistory.com/wp-content/uploads/2026/03/History-of-Venture-Investing-in-the-US-FINAL.pdf). He expected such investments to take ten or even twenty years to pay off, and he lost heavily on steel prefab houses and a Samoan tuna-canning venture[6](https://time.com/archive/6802473/business-space-age-risk-capitalist/).
His net worth is documented at three points: about $200 million in 1959[6](https://time.com/archive/6802473/business-space-age-risk-capitalist/); $62,581,225 in sworn net worth, with total assets of $64,154,238 for himself and his wife, as of August 23, 1974, plus life beneficiary status in two trusts with total assets over $116 million as of August 30, 1974[8](https://www.fordlibrarymuseum.gov/sites/default/files/pdf_documents/library/document/0011/1683471.pdf); and $1.5 billion per Forbes in 2003[9](https://www.independent.co.uk/news/obituaries/laurance-rockefeller-38820.html). When a leaked $33 million figure circulated in 1974, he explained the gap to the [Senate Rules Committee](https://www.edgepedia.org/united-states-senate-committee-on-rules-and-administration) as reflecting $20,500,000 in art and real estate already pledged for public use after his death, plus updated appraisals[8](https://www.fordlibrarymuseum.gov/sites/default/files/pdf_documents/library/document/0011/1683471.pdf).
## Conservation philanthropy and the parks
In 1940 [John D. Rockefeller](https://www.edgepedia.org/john-d-rockefeller), Jr. established the Jackson Hole Preserve to promote conservation and protect family land holdings in the Tetons of Wyoming, and Laurance became its first president[11](https://www.nps.gov/people/laurancerockefeller.htm). In 1949, as president of the Preserve, he made a gift to the federal government on behalf of his father of valley land that was included in [Grand Teton National Park](https://www.edgepedia.org/grand-teton-national-park)[10](https://rockarch.org/resources/about-the-rockefellers/laurance-s-rockefeller/).
In the [Virgin Islands](https://www.edgepedia.org/virgin-islands), in 1956 he made over to the federal government 5,000 acres of St. John, from which [Virgin Islands National Park](https://www.edgepedia.org/virgin-islands-national-park) emerged[9](https://www.independent.co.uk/news/obituaries/laurance-rockefeller-38820.html); the [National Park Service](https://www.edgepedia.org/national-park-service) records the donation as 5,000 acres of the island[11](https://www.nps.gov/people/laurancerockefeller.htm). That year the Rockefeller Brothers Fund gave $1 million to Jackson Hole Preserve, Inc. for development of the St. John tract for national park purposes[17](https://www.rbf.org/about/about-us/timeline).
He also worked through government. President Eisenhower appointed him chair of the Outdoor Recreation Resources Review Commission in 1958, and he served as a special emissary for President Johnson in the effort that created Redwood National Park[10](https://rockarch.org/resources/about-the-rockefellers/laurance-s-rockefeller/). The National Park Service credits him with creating and expanding several parks, including Virgin Islands National Park and Marsh-Billings-Rockefeller National Historical Park[1](https://www.nps.gov/articles/000/legacy-of-laurance.htm). His land gifts from Wyoming to the Virgin Islands amounted to hundreds of thousands of acres[2](https://www.nytimes.com/2004/07/12/business/laurance-s-rockefeller-passionate-conservationist-and-investor-is-dead-at-94.html).
The method carried over from his investing. As the Pugsley Medal biography puts it, he focused on leveraging his influence, being a catalyst, and priming the pump with matching grants so others became committed to a project also[18](https://aapra.org/Awards/Pugsley-Medal/Recipient-Biography/Id/14). In 2001 he donated the Laurance S. Rockefeller Preserve, formerly the JY Ranch, a 1,100-acre parcel within the Grand Tetons, to the National Park Service[1](https://www.nps.gov/articles/000/legacy-of-laurance.htm).
## Resorts and the conservation-investing link
His resort business sat next to, not on, his park philanthropy. He created seven complexes of resort developments, managed together as Rockresorts Inc., established in 1966; the National Park Service states these resorts were not linked to national park land but were private business[11](https://www.nps.gov/people/laurancerockefeller.htm). On St. John he set up the 600-acre Caneel Bay Plantation resort and donated the separate 5,000-acre park plot; in Puerto Rico he built the $9,000,000 Dorado Beach Hotel[6](https://time.com/archive/6802473/business-space-age-risk-capitalist/). His business papers date the Caneel Bay resort opening and National Park dedication to December 1, 1956, and the Dorado Beach Hotel opening to December 1, 1958[19](https://dimes.rockarch.org/collections/YE2cuEisedN5Wk5bdLbGK4). Rockresorts developed environmentally oriented resorts in Puerto Rico, the Virgin Islands, Hawaii, and Vermont[10](https://rockarch.org/resources/about-the-rockefellers/laurance-s-rockefeller/).
## Honors, other institutions, and legacy
His honors included the Medal of Freedom (1969), the [Congressional Gold Medal](https://www.edgepedia.org/congressional-gold-medal) (1991), and the Lady Bird Johnson Conservation Award for Lifetime Achievement (1997); in 2003 he became the first honorary citizen of the [British Virgin Islands](https://www.edgepedia.org/british-virgin-islands)[10](https://rockarch.org/resources/about-the-rockefellers/laurance-s-rockefeller/). When testifying in 1974 before a House committee inquiring into his brother Nelson's nomination as President Ford's vice president, he identified his primary occupation as "a concerned environmentalist"[18](https://aapra.org/Awards/Pugsley-Medal/Recipient-Biography/Id/14).
His institutional giving ran through established organizations: he chaired Memorial Sloan-Kettering Cancer Center from 1960 to 1982, was president and later chair of the Rockefeller Brothers Fund from 1958 to 1980, and was a trustee of the Alfred P. Sloan Foundation from 1960 to 1982[10](https://rockarch.org/resources/about-the-rockefellers/laurance-s-rockefeller/). He was appointed to the Palisades Interstate Park Commission in 1939, served as its president from 1970 to 1977, and resigned in December 1978[10](https://rockarch.org/resources/about-the-rockefellers/laurance-s-rockefeller/).
The National Park Service marked the twentieth anniversary of his death in 2024 with a commemoration of his park legacy[1](https://www.nps.gov/articles/000/legacy-of-laurance.htm).
