c. 1920 or earlier
Leaky Cauldron landlord
Tom (fl. 1938—1990s) was the landlord and barman of the Leaky Cauldron and was friendly with many wizards and witches that passed through the pub to get to Diagon Alley. He had run the Leaky Cauldron for a long time and had had the pleasure of meeting Harry Potter and former Minister for Magic Cornelius Fudge on more than one occasion. It is likely he had met other celebrities and political figures in the wizarding world such as Albus Dumbledore since his pub leads directly into Diagon Alley. He was very old by the time Harry Potter knew him, as he was mentioned by Albus Dumbledore in the late 1930s to Tom Riddle.
Tom was likely a pupil at Hogwarts School of Witchcraft and Wizardry and studied there at the age of eleven until he left and eventually became barman/landlord of the Leaky Cauldron some time before 1938. It is possible that Tom encountered Tom Marvolo Riddle (later to be known as Lord Voldemort) on his way to Diagon Alley for the first time, as Albus Dumbledore had told Tom Riddle to ask for him to get there.
In 1991, when Harry Potter and Rubeus Hagrid passed through the Leaky Cauldron on their way to Diagon Alley, Tom greeted Hagrid like an old friend. Other witches and wizards who were there at the time, (including Doris Crockford, Dedalus Diggle, and Quirinus Quirrell) began introducing themselves to Harry before Hagrid managed to get him away from all of them.
In 1998, Tom was greeted by Bellatrix Lestrange (who was really Hermione Granger using Polyjuice Potion) while on her way to Gringotts in Diagon Alley, and was surprised by how polite she was towards him.
Post-Second Wizarding War
Tom is described by Harry Potter upon sight as old, "quite bald" and resembling a toothless walnut.
Magical abilities and skills
- Wandless Magic: Tom was capable of performing simple wandless spells such as lighting a fireplace. 
- Non-Verbal Magic: On 7 August, 1993, Tom was able to turn off a car alarm using non-verbal magic.
Tom is diminutive of the name "Thomas" which means infidel or unfaithful. It was used as a formal male given name. It also means "twin."
It is also quite likely that J. K. Rowling intentionally gave him the same first name as Tom Riddle, as the fact was commented on by Albus Dumbledore. The similarity annoyed Riddle, who liked being independent.
Behind the scenes
- Tom was played by Derek Deadman in the film adaptation of Harry Potter and the Philosopher's Stone, while he was portrayed by Jim Tavaré in the film adaptation of Harry Potter and the Prisoner of Azkaban.
- Marian Opania played Tom in the Polish version of the first movie.
- There is a sharp difference between the two portrayals: in the film adaptation of Harry Potter and the Philosopher's Stone, Tom appeared quite normal with balding brown hair and regular features and acted quite normal too, but in the film adaptation of Harry Potter and the Prisoner of Azkaban, he looks like a hunchback, has gone completely bald and acts very oddly, laughing irrationally loudly at the wrong times and brutally grabbing Harry by the collar. This is likely due to the complete change in styles between the first and third films---while the first film, which had a very regular feel to it, was directed by Chris Columbus, the third film, which had a comparable quirkier feel to it, was directed by Alfonso Cuarón. This is the same with the consoles versions of both the LEGO games.
- In LEGO Harry Potter: Years 1-4, if one plays as Tom, and jumps while standing still, Tom will stumble upon landing and go forward several steps.
- In the Lego videogame, Tom can be unlocked in the first level of Year 1. First, you have to have unlocked Reducto. Then, in Gringotts, after you unlock the doors in the mainroom, use Reducto on the chest on the right. The one on the left holds Mr. Ollivander.
- In the film adaptation of Harry Potter and the Half-Blood Prince, when the Death Eaters pass their way from the Leaky Cauldron to Diagon Alley to kidnap Garrick Ollivander, it is unknown if Tom or a different associate was at the Leaky Cauldron.
