Marianne Liebmann was born in 1953, the youngest of three children of James Cargill and his wife, Mary Janet. She's the great-granddaughter of William W. Cargill, the founder of Cargill, who started the commodities business with one grain storage warehouse in Conover, Iowa, in 1865. Her siblings are James R. Cargill II and Austen S. Cargill II.

The billionaire graduated from Montana State University, in Bozeman. Her and her husband, Steve, were longtime owners and operators of the Langohr's Flowerland florists in the city until 2012, according to the Bozeman Daily Chronicle newspaper. At Cargill, Liebmann was part of a group of younger members of shareholding families who pushed for Cargill's dividend and operating structure to be reformed in the 1990s, according to a corporate history of Cargill by Wayne G. Broehl. As part of the reformation of corporate governance, she served on the Cargill board of directors from 1992 through 1998, according to Broehl. Liebmann also led a faction of about one-third of Cargill shareholders who successfully advocated for the company to allocate more than 10 percent of its annual income to dividends starting in the mid-1990s.
