Most people recognize the name Diane Keaton instantly. Fewer know that she was born Diane Hall — and even fewer know anything about the man behind that surname. Jack Newton Ignatius Hall was Diane Keaton’s father. He was not a celebrity, not a public figure, and not someone who sought the spotlight. But because of his famous daughter, his name keeps appearing in searches, genealogy records, and biographical profiles.
This article covers what is reliably known about Jack Newton Ignatius Hall — his birth, career, family, and death — while being honest about where the public record runs thin.
Who Jack Newton Ignatius Hall Was?
Jack Newton Ignatius Hall was a Nebraska-born civil engineer and real-estate broker. He is best known, if known at all, as the father of actress Diane Keaton. Outside of that connection, he lived a private professional life far removed from Hollywood.
Genealogy records identify him as the son of Chester Newton Hall and Marie Alice Powers. Most of what is publicly available about him comes from genealogy databases and secondary biographical sources — not from primary archives, official government records, or published obituaries that are currently accessible to the public.
It is also worth noting that other individuals share the name Jack Newton Hall. The person discussed in this article is specifically Jack Newton Ignatius Hall, identified through his family connection to Diane Keaton and the biographical details tied to that lineage.
Birth, Death, and the 1921 vs. 1922 Question
According to genealogy records on Genealogie Online, Jack Newton Ignatius Hall was born on February 6, 1922, in Omaha, Nebraska. His death is reported as September 1, 1990, in Corona del Mar, California.
Some secondary websites list his birth year as 1921 instead of 1922. The 1922 date is better supported by the available genealogy record, but it would not be accurate to call the matter fully settled. Neither date is currently confirmed by a primary government document or a verified obituary in publicly accessible sources.
It helps to understand what genealogy records actually are. Sites like Genealogie Online allow users to submit and compile family data. These entries can be very useful for establishing names, dates, and relationships — but they carry less authority than a birth certificate, census record, or newspaper obituary. That distinction matters when two different dates are circulating online and neither one has a primary document behind it.
For now, 1922 is the safer date to use, and February 6, 1922, is the more specific version supported by the genealogy record.
His Career in Civil Engineering and Public Works
Secondary sources describe Jack Hall as a civil engineer and public-works professional who later moved into real estate. According to these accounts, his career involved work connected to Los Angeles public agencies and Orange County flood-control projects. He is also associated with an engineering firm identified as Hall and Foreman Inc.
These details come from secondary biographical sources, not from primary employment records or company archives. They should be understood as reported background, not confirmed history.
That said, the career profile makes contextual sense. Postwar Southern California saw enormous infrastructure growth. Civil engineers during that era worked on roads, drainage systems, water management, and municipal planning — all areas that expanded rapidly as the region’s population grew in the 1940s through the 1960s. A Nebraska-born engineer relocating to California during that period fits a pattern common to that generation.
What is not documented is any specific project he personally designed or led. Attributing regional development to him directly would go beyond what the available sources support.
His Marriage and Four Children
Jack Newton Ignatius Hall married Dorothy Deanne Keaton. Together they reportedly raised four children: Diane, Randy, Dorrie, and Robin. These names are consistent across multiple sources, including Genealogie Online and NDTV’s biographical coverage of Diane Keaton.
The family represents two distinct surnames that sometimes cause confusion. Hall was the paternal branch — Jack’s family name. Keaton was the maternal branch — Dorothy’s maiden name. Both surnames appear in discussions of Diane Keaton’s early life, which is why it helps to understand where each one came from.
Beyond the names of the four siblings, private details about Randy, Dorrie, and Robin are not part of the public record in any well-documented way. This article sticks to what is independently confirmed.
Why Diane Keaton Was Born Diane Hall?
Diane Keaton was born Diane Hall in Los Angeles in 1946. Her birth surname came directly from her father, Jack Newton Ignatius Hall.
When she entered the entertainment industry, she needed a stage name. “Diane Hall” was already taken by another performer registered with Actors’ Equity Association, so she adopted her mother’s maiden name instead. That is how Diane Hall became Diane Keaton — a name that would go on to become one of the most recognized in American film.
This explains something that trips up a lot of online searches. When people look up “Diane Hall,” they are looking for the same person as “Diane Keaton.” The two names refer to one woman — the daughter of Jack Newton Ignatius Hall and Dorothy Deanne Keaton — at different points in her life and career.
It is worth keeping this section grounded in Hall’s family role. The stage-name story is really a story about family surnames, not just a Hollywood detail.
A Brief Timeline
- February 6, 1922 (reported): Born in Omaha, Nebraska
- 1940s: Marriage to Dorothy Deanne Keaton; family life begins
- 1946: Daughter Diane Hall is born in Los Angeles
- Later decades: Civil-engineering and real-estate career in California
- September 1, 1990: Death reported in Corona del Mar, California
This timeline is built from the sources available. Dates in the middle of his life — marriage year, career milestones, moves between states — are not currently documented in any reliable public record that this article can confirm.
What the Public Record Can and Cannot Tell Us?
Jack Newton Ignatius Hall was a private person. He did not seek public attention, give interviews, or leave behind a documented public trail the way his daughter did. Most of what circulates about him online comes from three types of sources: genealogy databases, secondary celebrity-biography websites, and YouTube videos about Diane Keaton’s family.
Genealogy databases are useful but limited. They establish relationships and basic dates, but the data is often user-submitted and not always verified against official documents.
Secondary biography sites repeat information from each other, and some introduce small errors — like the 1921 versus 1922 birth-year issue — that then spread across the web. YouTube biographies are even less reliable as standalone sources; they often repeat whatever appears on those same secondary pages.

The most accurate single-sentence summary of Jack Newton Ignatius Hall, based on available evidence, is this: he was a Nebraska-born civil engineer and real-estate professional, the husband of Dorothy Deanne Keaton, and the father of four children — including the actress who would become known to the world as Diane Keaton.
Final Thoughts
Jack Newton Ignatius Hall lived outside the public eye. He was not a celebrity, and he is not widely documented. His connection to Diane Keaton is the primary reason his name surfaces in searches, and that connection is well established through multiple genealogy and biographical sources.
What is less established are some of the finer details — the exact birth year, specific career projects, and personal history. This article has tried to present what is supported while being upfront about the gaps. That kind of honesty matters when writing about someone whose life was largely private and whose record is scattered across low-authority online sources.
He was, by all available accounts, a working professional who built a family in postwar California. His daughter went on to become one of the most celebrated actresses of her generation. That connection is real, documented, and the most meaningful thing the public record has to say about him.
