What happened to actor Bob Grant?
On 8 November 2003, Bob Grant was found dead inside his car in the garage of his home in Twyning, near Tewkesbury, Gloucestershire. The cause of death was carbon monoxide poisoning, ruled a suicide. According to the British Comedy Guide (entertainment reference site), Grant was 71 at the time of his death.
Discovery and circumstances of death
The Nostalgia Central retrospective (nostalgia and pop-culture archive) reports that Grant’s body was found in a fume-filled car locked in his garage. The location was confirmed as Twyning, Gloucestershire, by multiple sources including Wikipedia (community-edited biographical database).
Grant had lived with depressive illness for many years. IMDb’s biography (film and television credits database) states that he suffered from a depressive illness for a number of years. His death was the third documented suicide attempt. A 1987 episode saw Grant disappear from his Leicestershire home for five days; according to Wikipedia, it later emerged he had taken a ferry to Dublin intending to kill himself. A second attempt in 1995 involved carbon monoxide poisoning, for which he was treated.
Three documented attempts over 16 years, each methodically planned, paint a picture not of impulsive crisis but of long-standing, untreated despair that the public never saw behind the comic TV persona.
The pattern: Grant’s public identity as a light-entertainment figure never collided with his private reality until the obituaries ran. For a man who brought laughter to millions, the archival record shows a life increasingly hollowed by depression, with no public intervention ever reported.
What was Bob Grant’s real name?
Bob Grant was born Robert St Clair Grant on 14 April 1932, according to Wikipedia (community-edited biographical database). He was an English actor and writer, best known for playing bus conductor Jack Harper in the British sitcom On the Buses, as confirmed by his IMDb biography (film and television credits database).
Birth name and family background
Before his acting career, Grant supposedly trained at RADA for two years, according to an On the Buses Fan Club biography (fan-site archive), though this claim comes from a low-confidence source. The same fan-club biography reports he worked as a frozen food salesman and a bus driver before his fame, and served as a Lieutenant in the Royal Artillery. These early-career details lack corroboration from tier 1 or tier 2 sources.
The only source for Grant’s RADA training, his military service, and his pre-fame jobs is a single fan-club page with no editorial oversight. These claims should be treated as unverified.
The implication: Grant’s early biography rests on thin documentation. What’s certain — his birth name, his television role — is well-sourced. What’s rumoured about his pre-fame years remains plausible but not proven.
What was Bob Grant’s last acting role?
Grant’s last known acting credit came in 2003, the year of his death. According to IMDb filmography (film and television credits database), his final years saw him transition away from regular screen work toward writing, though detailed records of his writing career are sparse.
Final television and film appearances
Grant appeared in all 114 episodes of On the Buses between 1969 and 1973, plus the three film spin-offs: On the Buses (1971), Mutiny on the Buses (1972), and Holiday on the Buses (1973), as listed on IMDb’s Portuguese profile (film and television credits database). After the series ended, acting roles became rare.
The trade-off: The role of Jack Harper defined Grant so completely that it became both his career peak and a typecasting trap. After On the Buses, finding comparable work proved difficult, and his income and public profile shrank steadily over the following 30 years.
Are any of the On the Buses cast still alive?
As of 2025, the surviving cast member is Michael Robbins, who played Arthur Rudge (Blakey’s brother-in-law), though most of the main ensemble — including Bob Grant — have died.
Status of main cast members as of 2025
- Bob Grant (Jack Harper) — died 8 November 2003, aged 71
- Reg Varney (Stan Butler, the bus driver) — died 16 November 2008, aged 92
- Doris Hare (Mabel Butler) — died 10 September 2000, aged 95
- Michael Robbins (Arthur Rudge) — died 11 December 2022, aged 91
- Stephen Lewis (Inspector Cyril “Blakey” Blake) — died 14 January 2014, aged 87
- Anna Karen (Olive Rudge) — died 22 February 2022, aged 85
Why this matters: With the passing of Anna Karen in 2022 and Michael Robbins in 2022, the living connection to the main On the Buses cast is fading. For fans of British comedy, the show now exists entirely as archive footage and memory.
What was Bob Grant’s net worth?
No verified source has published Bob Grant’s net worth at the time of his death. The question appears frequently in search queries, but all available biographical sources — Wikipedia, IMDb, Nostalgia Central, the British Comedy Guide — omit any financial figures.
Earnings from On the Buses and later career
Grant’s main income came from his regular role in On the Buses and the three film spin-offs. He also pursued writing work in later years, but no reliable document identifies his income level or whether he earned residuals from syndication. The fan-club biography suggests he lived in Twyning, Gloucestershire, in a modest home, but property records have not been linked to his estate in any published source.
Net worth queries about Bob Grant run into a wall of missing data. No reputable archive, probate record, or family statement has been made public. Any number circulating online is speculation.
For readers looking for a definitive number: it does not exist in the public record. The absence itself tells a story — Grant’s later life was quiet enough that no financial story was ever reported.

Bob Grant brought laughs to British living rooms for five years. But his story is not a comedy. It’s a documented case of a public figure whose private suffering was severe, prolonged, and ultimately fatal. For fans of classic British television, the lesson is clear: the smiling face on screen was, for Grant, a mask that never came off until the garage door went up.
