Anyone who watched The Nanny remembers the butler with the crisp English accent was actually an American actor from Arkansas. That contradiction made Daniel Davis a familiar face in the 1990s and a cult favorite again when Star Trek fans recognized him as Professor Moriarty, and this profile sorts the verified facts from the assumptions — his real age, nationality, and why his net worth stays unconfirmed.
Born: November 26, 1945 · The Nanny: 1993–1999 · Known role: Niles the butler · Star Trek role: Professor Moriarty · Age in 2026: 80 · Official net worth: Not disclosed

Daniel Davis at a glance
Seven facts, one pattern: the reliable record is all career, and the personal and financial details stay off the page.
| Field | Detail |
|---|---|
| Full name | Daniel Davis |
| Born | November 26, 1945 |
| Birthplace | Gurdon, Arkansas, U.S. |
| Occupation | Actor |
| Known for | Niles in The Nanny; Professor Moriarty in Star Trek: The Next Generation |
| Stage credential | 2000 Tony Award nomination, Wrong Mountain |
| Net worth status | Not publicly disclosed; publisher biography lists credits, not finances (Penguin Random House (publisher biography)) |
The implication: the public record is long on credits and short on personal data — a balance that shapes every answer below.
How much is Daniel Davis worth?
The short answer: no verified figure exists. Daniel Davis has never published a net worth, no credible financial outlet has documented one, and the numbers that appear in search results come from celebrity-net-worth aggregators, not from Davis or his representatives.
Where do net worth estimates come from?
- Aggregator sites combine guesses about syndication residuals, guest fees, and real estate with no tax records, contracts, or statements from Davis himself.
- The one documented financial-adjacent fact is the length of his career: stage, television, and film work spanning several decades (Penguin Random House (publisher biography)).
Any “Daniel Davis net worth” figure you find is an estimate, not a confirmation. His documented public record is a résumé, not a bank statement — and the résumé never included salary numbers.
What roles built Daniel Davis’s career income?
- Six seasons as Niles on The Nanny from 1993 to 1999, his highest-profile television role.
- A 2000 Tony Award nomination for Wrong Mountain, a Broadway credential that stage actors list for decades.
- Film work including Christopher Nolan’s The Prestige (2006) (Rotten Tomatoes (review aggregator)).
- Earlier television regular work on the drama Texas in 1980 (Rotten Tomatoes).
The pattern: Davis’s income story is a credits list, not a financial statement. The public record says what he was paid for — not what he was paid.
How old was Daniel Davis when he played in The Nanny?
Davis was born on November 26, 1945, which puts his Nanny years in his late 40s and early 50s. The show ran from 1993 to 1999 (TV Insider), making him 47 at the premiere and 53 at the finale. He appeared in roughly 145 episodes across six seasons (IMDb).
How old is Niles supposed to be in The Nanny?
- The show never gives Niles a fixed canonical age.
- He is written as a longtime household butler, which makes him read as older and wiser than the other characters, but no birthday or birth year is ever stated.
- Davis’s own age — late 40s when the series began — made the character feel seasoned without needing a specific number.
How old is Dan Davis?
- If the question means the actor Daniel Davis: he was born on November 26, 1945, so he is 80 in 2026.
- If it means Daniel Davis the visual-effects artist, that is a different person with a different career.
- The actor’s Nanny-era age is well documented; the fictional Niles’s age is not, which is why the two questions keep getting mixed up.
The trade-off: Niles never needed a birthday because his role was timing and sarcasm, not biography. Davis, by contrast, has a firmly documented birth date — the accent was the fiction, not the man.
Is actor Daniel Davis British?
No. Davis is an American actor from Arkansas, and the English accent is a performance. TV Insider’s actor profile is direct: “Niles was written and performed as a British butler, although Davis is American and comes from Arkansas” (TV Insider).
Who did Daniel Davis play in The Nanny?
- Niles, the British butler on The Nanny who spent six seasons trading barbs with the household.
- The character’s English accent was central to the show’s comedy and to Davis’s most famous screen credit.
What role did Daniel Davis play in Star Trek?
- Professor James Moriarty, the holographic adversary in Star Trek: The Next Generation.
- Davis appeared in two episodes — “Elementary, Dear Data” and “Ship in a Bottle” (Wikipedia).
- Like Niles, the role used a received-pronunciation English accent, one more reason some viewers assumed the actor was British.
A kid from Arkansas built two of his most recognized characters on a voice borrowed from English theater. The accent that made him famous was a tool, not a biography.
What this means: the accent is why the rumor survives. The performance was so consistent that the man behind it became invisible — exactly what a character actor is supposed to do.
Is actor Daniel Davis married?
There is no public record of Daniel Davis being married, and he has not confirmed a current spouse. His publisher’s author biography and database profiles list credits, not relationships, so the personal side of his life stays off the record.
Who is Daniel Davis’s wife?
- No verifiable wife or partner is named in any sourced biography reviewed for this article.
- Davis rarely discusses his personal life in interviews, and no major outlet has documented a marriage.
- The absence of a name is not a confirmation of any marital status — it is a confirmation that the information is not public.
The catch: for a man whose voice is famous, Davis has been unusually quiet about everything else. The gaps in his biography read as boundaries, not oversights.
What is Daniel Davis doing now?
Davis is still working, mostly in episodic guest roles rather than series leads. The 2020 Nanny reunion special lists him in its cast, and his scripted work includes a credited role on The Blacklist (IMDb).
At 80, Davis is picking guest-sized roles over comebacks. The Blacklist credit and a 2025 Star Trek Day video message suggest a performer who stays connected to his audience without chasing the spotlight.
Why didn’t Daniel Davis attend The Nanny reunion?
- The 2020 HBO Max reunion special lists Davis in its cast, so claims that he skipped the reunion need context.
- If a different reunion event is meant, no official absence statement from Davis or the production was published.
- Unspecified “missed reunion” stories should be treated as unverified.
Did Daniel Davis appear in The Blacklist?
- Yes — Davis has a credited role on The Blacklist.
- The part fits a pattern of post-Nanny work: episodic guest appearances in established shows rather than new regular roles.
- For episode-level details, his IMDb filmography remains the public reference point.
Why this matters: Davis chose range over fame. The Nanny made him recognizable; the decades around it made him hard to pin down — which is why “what is he doing now?” keeps surfacing in search results.
Daniel Davis career timeline
The dates below compile the facts cited above — Wikipedia for his birth and Star Trek credits, TV Insider for the Nanny years, and IMDb and Rotten Tomatoes for screen work.
- — Born in Gurdon, Arkansas.
- — First appears as Professor Moriarty in Star Trek: The Next Generation (IMDb).
- — The Nanny premieres; Davis begins his run as Niles (TV Insider).
- — The Nanny ends after six seasons.
- — Appears in Christopher Nolan’s The Prestige (Rotten Tomatoes).
- — The HBO Max Nanny reunion special airs with Davis in its cast.
- — Star Trek Day features a video message from Davis thanking caregivers.
The pattern: gaps of years between credits, but no retirement announcement. Davis’s timeline looks like a stage actor’s — busy in bursts, quiet in between.
Confirmed facts vs. what’s unclear
The classification below follows a simple standard: confirmed means a reliable published source documents it; unclear means no verifiable source does.
Confirmed facts
- Born November 26, 1945, in Gurdon, Arkansas (Wikipedia)
- American actor; Niles’s English accent was a performance, not his natural voice (Wikipedia)
- Played Niles on The Nanny from 1993 to 1999 and Professor Moriarty in Star Trek: The Next Generation
- Received a 2000 Tony Award nomination for Wrong Mountain (IMDb)
What’s unclear
- Exact net worth — no official disclosure exists, and online figures are estimates.
- Current relationship status — no spouse or partner is publicly documented.
- A reported Moriarty reprise in Star Trek: Picard‘s third season has not been independently confirmed.
- A 1974 Great Performances credit, according to Rotten Tomatoes’s career summary (Rotten Tomatoes).
- Why he might have missed an unspecified reunion event — no official explanation exists.
The pattern: everything about Davis’s work is documented; almost everything about his money and private life is not. That split is the real story of researching him.
What the sources say
Two sources frame the contradiction that defines Davis’s career.
“Davis used a received-pronunciation English accent for Professor Moriarty, as he did for Niles.”
“Daniel Davis’s acting career includes stage, television, and film work spanning several decades.”
The thread running through both: Davis’s defining tool is a voice that is not his, used with such consistency that it created a public identity separate from the private man.
The takeaway
The reliable version of Daniel Davis’s story is short: an American actor who spent six seasons on The Nanny and two Star Trek episodes playing English-accented characters, with a Tony nomination and a multi-decade stage career behind him. The unreliable parts are just as easy to name — net-worth figures, relationship details, and reunion gossip are all unverified. For anyone writing about Davis in 2026, the choice is clear: cite the documented credits and label every financial or personal claim as unconfirmed, or keep recycling estimates the actor himself has never endorsed.

Davis trained extensively on stage — including the Arkansas Arts Center, the Oregon Shakespeare Festival, the Stratford Shakespeare Festival, and six years with the American Conservatory Theater, where he also taught acting.

Why did The Nanny get canceled?
The series wrapped after its sixth season in 1999. No single official explanation was published at the time; Davis’s role as Niles ran through the final season.

No. He appeared as Professor Moriarty in two episodes — “Elementary, Dear Data” and “Ship in a Bottle” — rather than as a member of the regular cast.
