Andrews already had some experience in production in the newly discovered oilfields of western Pennsylvania when, in 1862, he approached two Cleveland produce merchants to become stockholders in a new enterprise.
[1] Ida M. Tarbell, an early investigative journalist and the author of The History of Standard Oil, described Andrews as "a mechanical genius", who "devised new processes" to create a better product.
[2] While he left Standard Oil early, he did try to display his wealth by building a mansion on Cleveland's Euclid Avenue, also known as "Millionaire's Row".
His better-known partners, Rockefeller and Henry Morrison Flagler, are credited with the marketing strategies and schemes that capitalized on Andrews' technical expertise.
The last remaining influential shareholder, Henry Huttleston Rogers, decided as Flagler to diversify his investments, he embarked on the railroad business and set up the Virginian Railway.
[3] His funeral was held in Cleveland, and he was temporarily interred in the Wade Chapel receiving vault at Lake View Cemetery.
