Key Identity and Background
Katherine Liberman Mnuchin
Steven Mnuchin’s first wife is Katherine Liberman Mnushin (often referenced in filings and coverage as Katherine Liberman). She is an interior designer and businessperson who met Mnuchin in the 1990s. They married in the late 1990s, had three children, and later divorced prior to his marriage to Marilyn Johnson in 2016. Her professional focus has been in interior design, and she has maintained a largely private public profile compared to his later spouse.
Verified Relationship Timeline
Their marriage occurred in the late 1990s; exact year varies by source reporting, but multiple legal and biographical references confirm they wed before 2000. The couple had three children together and divorced in the mid-2010s, well before Mnuchin’s 2017–2021 service as Treasury Secretary. In 2016, Mnuchin married Marilyn Nicole Johnson. No credible legal or financial documents suggest ongoing spousal support arrangements publicly disclosed beyond standard divorce privacy.
