Concrete actions in order of leverage-per-hour. Phone numbers and emails verified from public sources in April 2026. Private individuals (the wives, Christiane) require a family-network approach — not listed here because cold-call is not the right channel.
1. Ebsworth Park — email today (easiest win)
Do first
Frank Lloyd Wright House in Ebsworth Park (Kraus House), 120 N Ballas Rd, St. Louis 63122 · 75/25 Anniversary Year is in progress
Why it's the first call: low-friction, high-reward. They know Barney better than any institution does. They are in the middle of a year-long public commemoration with three confirmed dates. A short introductory email establishes you as the family biographer and opens their archive of 25 years of board correspondence, docent notes, and possibly correspondence from Barney himself.
Three confirmed 2026 dates the biographer should attend or document:
• April 1, 2026 — Reopening for tours after the six-month roof restoration (cedar shingles restored to FLW original spec, $100K matching grant). First public viewings of the restored roof. Tour reservations required.
• May 3, 2026 — Joanne & Alan Kohn Lecture at the Saint Louis Art Museum (not the Park itself): “Givenchy's Rehabilitation of Frank Lloyd Wright's Anderton Court Shops.” Free to the public. Filmable, attendable, networking opportunity.
• September 13, 2026 — Preserving What's Wright benefit at the Ebsworth Park grounds. The marquee anniversary event of the year. Tickets when announced.
📞 (314) 822-8359 · ✉ info@ebsworthpark.org · secondary contact: lnunes@ebsworthpark.org · site developer: Studio 2108
Suggested script: “I'm the WholeTech team, Barney Ebsworth's first cousin. I'm writing the definitive biography of him — the 4th edition is in active drafting. I'd like to visit the Park during the 75/25 year (perhaps around the May 3 Kohn Lecture or the Sept 13 benefit), speak with the board about Barney's intentions for the gift, and consult any correspondence you may hold from him. I'd also like to discuss becoming a 2026 Anniversary Member to support the work. What's the best way to arrange?”
2. Peter Ueberroth — URGENT (he is 88)
Time-sensitive
Best man at Barney's 1992 wedding to Pam; former MLB Commissioner; chaired 1984 LA Olympics
Why it's urgent: Peter Ueberroth is the single most valuable human source the project will ever have access to. Decades-long friendship with Barney, best man at the wedding to Pam. His testimonial transforms every pitch. He is 88 years old. The window is biological.
📞 The Contrarian Group Inc · (949) 720-9646 · 23 Corporate Plaza Dr, Suite 240, Newport Beach, CA 92660 · website thecontrariangroup.com (request email through receptionist)
Suggested script: “Good morning, my name is the WholeTech team. I'm Barney Ebsworth's first cousin and I'm writing the definitive biography of him. I know Mr. Ueberroth was Barney's best man at his 1992 wedding. I'd be grateful for the opportunity to speak with Mr. Ueberroth — even briefly — about his friendship with Barney. What would be the best way to make that happen?”
3. Smithsonian Archives of American Art — the oral history
Unlocks the book
Holds Barney's 2017 oral history (interviewer: Mija Riedel) — the single largest primary source the 4th edition does not yet draw on
Why it matters: Two full days of Barney on the record at Hunts Point, recorded in May 2017, two weeks before he married Rebecca. Audio is available by appointment at the D.C. Research Center. A transcript may also be accessible. This is the piece of primary-source research that would most substantially advance the 4th edition.
✉ Research request via aaa.si.edu/services/questions · Reading Room requests via Aeon research system · Research centers: Washington DC and New York
Suggested action: submit a Research Request through the Aeon system identifying yourself as the biographer-of-record, family relation, and requesting access to the Mija Riedel/Barney A. Ebsworth 2017 oral history. A reading-room appointment in DC is the likely path; a transcript if one exists is the prize.
4. Olson Kundig — the Hunts Point house archive
Visual goldmine
Jim Olson designed the Hunts Point house specifically for Barney's collection
Why it matters: Olson Kundig will have the original design drawings for the Hunts Point house plus (almost certainly) professional photography of the house with the paintings installed. That photography is the single most visually powerful documentary/book asset in existence for this project. Jim Olson himself is alive and may be interviewable.
✉ press@olsonkundig.com · 📞 +1 206 624 5670 · Ciara Cronin, Director of PR & Communications · 159 South Jackson St., Suite 600, Seattle, WA 98104
Suggested script: “Hi Ciara, I'm writing a definitive biography of Barney Ebsworth. Jim Olson designed his Hunts Point house in the early 2000s. I'd love to request (a) permission to use Olson Kundig photography of the house in the book and (b) an interview with Jim himself if he's available. Could you point me to the right process?”
5. Maxine Clark — Build-A-Bear, St. Louis
Local & warm
Founder of Build-A-Bear Workshop; Barney was an early $4.5M investor via Windsor, Inc.
Why it matters: St. Louis-based, reachable, personally knew Barney, has spoken publicly about her early backers. An interview is the kind of warm source that establishes Barney as a real business partner (not just a collector) and opens her St. Louis network for further introductions.
✉ via clarkfoxstl.com contact form (Clark-Fox Family Foundation — she is CEO) · St. Louis, MO
Suggested script: “Dear Ms. Clark, I'm Barney Ebsworth's first cousin and I'm writing his definitive biography. I know Barney was an early backer of Build-A-Bear through Windsor, Inc. in 1997. I'd love 30 minutes of your time to talk about what he was like as an investor and a friend. I'll come to St. Louis to do it.”
6. Crystal Bridges / Alice Walton's team
Testimonial possibility
Alice Walton's museum; Barney publicly defended her Ozarks location
Why it matters: Barney defended Walton's decision to build Crystal Bridges in Bentonville against East Coast art-world criticism. A brief written testimonial from Alice Walton (or even a curator) about her friendship with Barney would be a quoteable blurb for the book jacket and pitch documents.
✉ media@crystalbridges.org · 📞 (479) 418-5700 · 507 SE E St, Bentonville, AR 72712
Suggested script: Start through the media channel — Alice Walton's personal office is tighter-held, but the museum PR team can forward a biographer's inquiry to her office if the request is specific and modest.
7. Georgia O'Keeffe Museum Research Center — Doris Bry papers
O'Keeffe chapter
May hold Doris Bry correspondence and Barney-as-agent records
Why it matters: Part VIII of the 4th edition is the Abiquiu chapter. The Research Center may hold Doris Bry's correspondence with Barney, agent-file records, and curatorial notes on the paintings Barney eventually gifted to SAM. Appointments must be scheduled five business days in advance.
✉ contact@gokm.org · 📞 (505) 946-1000 · Library & Archive, 135 Grant Ave, Santa Fe, NM 87501 · Mon-Fri 9am-12pm by appointment
8. Seattle Art Museum Libraries & Archives
SAM controversy
Recipient of partial Ebsworth bequest; the 2007 promised 65 vs. actual gifts controversy lives here
Why it matters: Part XII needs to handle the SAM controversy honestly. Internal SAM correspondence about the Ebsworth bequest is likely in their institutional archives (Dorothy Stimson Bullitt Library or SAM historical records). Public-records paths exist if the direct route closes.
✉ libraries@seattleartmuseum.org · 📞 206-654-3210 · by-appointment only
9. Missouri Historical Society — Frauenthal archives
Part I anchor
May hold “Ask Barney about St. Louis” (1904) — the elder Frauenthal's guidebook
Why it matters: A photograph of the actual 1904 guidebook is the visual centerpiece of Part I. MHS also holds genealogical records relevant to the Frauenthal family line.

10. Steve Martin — via WME (later, with manuscript in hand)
Later
Actor, friend of Barney's, fellow collector
Why wait: Steve Martin is a marquee endorsement opportunity, but cold-asking a movie star for a quote on an unfinished book is the wrong approach. The right time to reach out is when the manuscript is substantially complete and you can offer him a galley copy and ask for a jacket blurb. Represented by Andrew Finkelstein at William Morris Endeavor (WME). Current publicist: Allison (last name partially redacted in public sources).

11. American Masters (PBS/THIRTEEN) — NOTE: Susan Lacy left in 2013
Later
PBS biographical documentary series
Important correction: Susan Lacy moved from American Masters to HBO in 2013. Current American Masters is still at THIRTEEN/WNET. For Susan Lacy herself, HBO is the right contact. For American Masters submissions, the THIRTEEN pressroom is the path.
