Direct answer: Dru Hammer is an Oklahoma-raised author, businesswoman, philanthropist, and mother of Armie and Viktor Hammer. She married Michael Armand Hammer in 1985 and later divorced him. Her recent public work centers on Christian faith, charitable projects, and her memoir Hammered.
Who Is Dru Ann Mobley?
She first became publicly connected with the Hammer family through her marriage to Michael Armand Hammer. Michael was the grandson of industrialist Armand Hammer, whose business career centered heavily on Occidental Petroleum. Their marriage placed her inside a family already associated with enormous wealth and public attention.
Today, she uses the name Dru Hammer in her public work and published memoir. Her profile now extends beyond her former marriage and her son’s acting career. Her projects include charitable work, faith-based outreach, property renovation, writing, and public speaking.
Her Early Life in Tulsa, Oklahoma
Dru grew up in Tulsa within a Christian household led by Douglas and Donna Mobley. According to her later accounts, her father combined business interests with a religious ministry. Her mother’s regular Bible study also influenced the religious outlook Dru describes today.
She attended Oklahoma State University before beginning her adult career. Contemporary reporting from the 1980s identified her as an Oklahoma State graduate with banking experience. Historical reports also described her father as a Tulsa real estate developer and banker.
These details matter because several newer biographies conflict with them about her early career. Some recent pages describe occupations without reliable sources. Contemporary reporting supports banking and fitness-related work more clearly than several newer claims.
Marriage to Michael Armand Hammer
According to contemporary and later accounts, Dru met Michael Hammer during an airplane journey in 1984. They became engaged within months, and they married in Tulsa on January 12, 1985. The First Methodist Church hosted the ceremony.
The marriage brought her into the dynasty Armand Hammer established. Michael worked within Occidental Petroleum and later handled major family interests. Washington Post reporting from 1996 also documented Dru’s influence on the family’s growing involvement with Christian organizations.
The couple eventually separated after more than two decades together. Dru has since discussed marital betrayal and the divorce from her own religious perspective. Her memoir presents that period as a major turning point in her financial and personal independence.
Her Children, Armie and Viktor Hammer
Dru and Michael had two sons, Armie Hammer and Viktor Hammer. Armie was born in 1986 and later pursued acting rather than the family’s traditional business path. Viktor built a much lower-profile professional life in finance.
The family spent periods living outside the continental United States, including time in the Cayman Islands. Older reporting described Michael and Dru raising their sons there during the 1990s. Armie’s biographies also document his childhood connections with Los Angeles and the Cayman Islands.
Public interest in Dru grew considerably because of Armie’s film career and later controversies. Her recent memoir discusses those experiences from a mother’s perspective. That connection explains much of today’s search interest, but it covers only part of her own public history.
Business, Property Renovation, and Charitable Work
Her professional interests eventually expanded into property renovation and design. Museum of the Bible says she has renovated more than 40 properties. She has described the work as an unexpected career that developed alongside other family responsibilities.
She also spent years participating in charitable and religious organizations. Museum of the Bible identifies her as a former corporate secretary and board member of the Armand Hammer Foundation. The organization says she held those roles for 22 years.
Her charitable involvement later included work with women through the Los Angeles Dream Center. CBN reports that she worked with women facing addiction and survivors of sex trafficking. She later founded the Hammered Heart Foundation to support people experiencing difficult circumstances.
The Hammered Memoir
Dru released Hammered, a memoir centered on marriage, loss, faith, family, and rebuilding her life. Museum of the Bible hosted an event for the book in January 2025. The museum described the memoir as covering her Oklahoma childhood through her marriage into the Hammer dynasty.
The book also addresses financial independence after a difficult divorce. Promotional information describes real estate, family experiences, public scrutiny, and religion as major subjects. Her Christian faith provides the central framework through which she interprets those events.
That makes the memoir useful for understanding her present public identity. Earlier coverage often presented her mainly through Michael or Armie Hammer. Her recent appearances instead emphasize her own experiences, foundation, property work, and religious projects.
Dru Ann Mobley Age and Net Worth: What Is Confirmed?
A precise birth date is difficult to confirm from strong primary or established sources. Several newer biography websites publish estimated ages, but their claims conflict. It is safer to avoid presenting an exact age unless a dependable public record confirms it.
Her net worth presents the same problem. Search results include websites claiming large dollar estimates without documented financial records. Don’t treat those figures as established facts, especially when sources provide no reliable calculation. For a sourced example of how a net worth breakdown should read, see the Spike Lee net worth guide.
What can be verified is her long history around business, property renovation, foundations, and the Hammer family. Those activities do not establish a specific personal net worth. Readers should treat unsourced wealth estimates as speculation rather than biography.
Faith and Her Public Work Today
Christianity has been a consistent theme throughout Dru’s public accounts. CBN describes a religious upbringing in Tulsa and extensive faith-based work during adulthood. Her memoir also places faith at the center of her response to divorce and family difficulties.
Her recent projects connect that religious focus with technology and charitable outreach. Museum of the Bible publicized her Bible-focused digital project alongside her memoir event. It also identifies her as the founder of Hammered Heart.
That combination helps explain why her profile has changed during recent years. She remains connected with a famous family, but her current messaging focuses more strongly on her own work. Writing, philanthropy, faith, and personal rebuilding now shape much of that public identity.
