Rose Blumkin ("Mrs. B")

Rose Blumkin (1893–1998) was the founder of Nebraska Furniture Mart and one of the most legendary figures in Berkshire Hathaway’s history. Known for her relentless work ethic and "unscientific" but superior business instincts, she served as a benchmark for Buffett's definition of a "Superstar" manager.

📍 Origin

Buffett’s formal association with Mrs. B began with the 1983 acquisition of Nebraska Furniture Mart, but he had admired her business for decades.

• Genetic Excellence: Buffett frequently praised her "business genetics," as her son Louie Blumkin and her grandchildren continued her legacy of shrewd buying and character.
• The Acquisition: In 1983, Buffett purchased 90% of NFM for $55 million. The contract was a simple, one-page document. Mrs. B continued on as Chairman.

📖 The Story

• The Escape: Left Russia in 1917 at age 23 with no formal education and no English.
• The Dream: Founded Nebraska Furniture Mart in 1937 with only $500 in savings.
• The "Managerial Kiss": In the early days, she sold her own home furniture to pay creditors, a level of commitment Buffett cited as being "not taught at business schools."
• The Courtroom Triumph: Successfully fought Fair Trade lawsuits by proving she could sell carpets at a discount and still make a profit. Famously sold the judge $1,400 worth of carpet after winning her case.

🧠 Management Style

• Volume over Margin: Focused on providing the lowest price and highest volume, often frustrating competitors who tried to boycott her.
• The Sales Floor: Even after selling 90% of the business to Berkshire at age 90, she remained on the sales floor seven days a week, personally outselling entire departments.
• The 1989 Update: At age 96, Mrs. B "retired" from Nebraska Furniture Mart but immediately proved that "retirement" was not part of her vocabulary. She started a new business, "Mrs. B's Clearance and Factory Outlet," across the street from NFM, once again proving her unmatched entrepreneurial drive.
• The 1992 Reunion: At age 99, Mrs. B sold her competing business and building back to NFM, bringing her operations back under the Berkshire tent. Buffett famously stated that he snapped at the deal but was sure to get her to sign a non-compete agreement this time, noting that signing a non-compete at 99 years old adds one more record to her Guinness Book of World Records status!
• 100th Birthday: On December 3, 1993, Mrs. B turned 100. Because the store was scheduled to be open on the evening of her birthday, she chose to postpone her birthday party so she could work, yet another testament to her dedication. 1993 Letter
• Antidote to Disruption: Mrs. B's refusal to diversify or follow fads made her the antithesis of The Institutional Imperative and a practitioner of Non-Gin Rummy behavior.

💡 Legacy

Mrs. B represents the epitome of a Wonderful Business manager: one who builds a moat through efficiency and customer value rather than just capital.

"I’d rather wrestle grizzlies than compete with Mrs. B and her progeny." — 1983 Letter
