Without the time to research deeply this morning, he was a private entrepreneur of sorts with seed grains which left his descendants well off, and would have created some uproar if he had become President because he leaned more than a bit left of Progressives.
From the Wikipedia article, Legacy section:
"During his time in the Roosevelt administration, Wallace became a controversial figure, attracting a mix of praise and criticism for various actions.[205][75] He remains a controversial figure today.[206][207][208] Historian Arthur M. Schlesinger Jr. pronounced Wallace to be both "an incorrigibly naive politician" and "the best secretary of agriculture the country has ever had".[209] Journalist Peter Beinart writes that Wallace's "naive faith in U.S.-Soviet cooperation" damaged his legacy. Historian Andrew Seal lauds Wallace for his focus on combating both economic and racial inequality.[207] Wallace's vision of the "Century of the Common Man", which denied American exceptionalism in foreign policy, continues to influence the foreign policy of individuals like Bernie Sanders.[210] In 2013, historian Thomas W. Devine wrote that "newly available Soviet sources do confirm Wallace's position that Moscow's behavior was not as relentlessly aggressive as many believed at the time". Yet Devine also writes that "enough new information has come to light to cast serious doubt both on Wallace's benign attitude toward Stalin's intentions and on his dark, conspiratorial view of the Truman administration".[211]
Alex Ross of The New Yorker writes, "with the exception of Al Gore, Wallace remains the most famous almost-president in American history".[74] Journalist Jeff Greenfield writes that the 1944 Democratic National Convention was one of the most important political events of the twentieth century, since the leading contenders for the nomination might have governed in vastly different ways.[99] In The Untold History of the United States, Oliver Stone argues that, had Wallace become president in 1945, "there might have been no atomic bombings, no nuclear arms race, and no Cold War".[212][213] By contrast, Ron Capshaw of the conservative National Review argues that a President Wallace would have practiced a policy of appeasement that would have allowed the spread of Communism into countries like Iran, Greece, and Italy.[214]
The Henry A. Wallace Beltsville Agricultural Research Center in Beltsville, Maryland, the largest agricultural research complex in the world, is named for him. Wallace founded the Wallace Genetic Foundation to support agricultural research. His son, Robert, founded the Wallace Global Fund to support sustainable development.[206] A speech Wallace delivered in 1942 inspired Aaron Copland to compose Fanfare for the Common Man.[74] The Franklin D. Roosevelt Presidential Library and Museum's grounds in Hyde Park, New York, include the Henry A. Wallace Visitor and Education Center at its north end. "
