Amos Diggory was a wizard who worked in the Department for the Regulation and Control of Magical Creatures in the British Ministry of Magic. He and his wife lost their son Cedric in June of 1995, when he was murdered by Peter Pettigrew on Lord Voldemort's orders.
Amos was born into the wizarding Diggory family. He was the only child of his parents. Amos most likely attended Hogwarts. He started working in the Ministry of Magic sometime after leaving school.
The Diggory family lived either in or near to the village of Ottery St Catchpole, near the Weasley and Fawcett families. In 1994, Amos and his family attended the Quidditch World Cup. After a Death Eater riot broke out, a team of witches and wizards, including Amos, found the house-elf Winky lying beneath the Dark Mark and questioned her about what happened.
He performed Prior Incantato on the wand of Harry Potter to deduce who had used the Morsmordre spell. Later, he asked Arthur Weasley to help Alastor Moody out of trouble; unbeknownst to him, this was the day Moody was kidnapped by Barty Crouch Jr. Amos simply thought it was another false alarm from the paranoid Moody and wanted to ensure that the former Auror's new job at Hogwarts would not be jeopardised.
That same year, Amos's son Cedric was selected as Hogwarts' champion in the Triwizard Tournament, something for which Amos was extremely proud. However, Harry Potter's name also came out of the Goblet of Fire. Many people erroneously believed that Harry intentionally tried to cheat Cedric and Hufflepuff house out of their deserved glory, as he was too young to be selected and received the most publicity. Amos was openly rude to Harry before the tournament's Third Task. This infuriated Molly Weasley, with whom Amos almost had a public confrontation, but his wife restrained him.
Harry and Cedric considered themselves to be equally winners at the end of the tournament, thus they both touched the Triwizard Cup, unwittingly taking a Portkey as part of the trap Lord Voldemort set for Harry. Voldemort ordered his servant Peter Pettigrew to kill Cedric. Harry managed to escape the graveyard with Cedric's body, returning him to his devastated parents (Amos openly sobbed later while Harry explained what happened). Amos thanked Harry for returning Cedric's body, and assured him that they did not blame Harry for his death. Harry tried to give them the prize money that came with winning the tournament, but they refused it. Amos subsequently had little to do in the war against Voldemort; his son was ultimately avenged when Voldemort was defeated. 
By 2020, Amos was living at St Oswald’s Home for Old Witches and Wizards. One of his carers was Delphini, who affectionately called him uncle. One day, Amos heard about how Harry Potter may have found a time-turner. He decided to schedule a meeting with him. However, each meeting kept getting changed to a later date at the last minute. Several months later, Amos decided to visit Harry at his home in the middle of the night. Delphini helped Amos and he apprehended Harry when he returned home. Amos begged Harry to use the time-turner to go back in time and save Cedric. Harry politely declined, stating he couldn’t meddle with time. Amos thought Harry was partly responsible for the death of Cedric because Voldemort never wanted Cedric, he wanted Harry. He was devastated to hear that Voldemort considered Cedric to be “the spare”. Harry lied to Amos and told him the story about a new time-turner was untrue. Amos thought Harry to be cold.
Unbeknownst to Amos, the conversation was overheard by Albus Potter. Albus decided to visit him and tell him he and his friend Scorpius Malfoy would be happy to go back in time and save Cedric. Amos did not take them seriously at first considering they were only children, but he was convinced they could when Delphi persuaded him and made him see even children could change the future, reminding him of the great things that happened in the Second Wizarding War.
The plan to save Cedric inevitably changed the future, but not to the better one Amos had hoped for. It is unknown what happened to him in the changed timelines but they were eventually undone, leaving Amos without a son again. It is not known how he felt after this, but he still lamented about Cedric and would have no choice but to accept Cedric was gone.
Amos is later visited by Harry and Draco Malfoy who believe he is responsible for their sons going missing again. They found out Amos had sent them owls which Amos denies and says he has no idea where they have gone. They tell Amos the children were last sighted with his niece Delphi, which surprises Amos, since he tells him them he does not have a niece.
Amos was described as being "tall"; he had a ruddy face and a "scrubby" brown beard, and wore oval-shaped glasses.
Personality and traits
Amos was extremely proud of his son, Cedric, to the point of boasting about his accomplishments at every given opportunity. He became quite angry and disrespectful when Cedric was not even given a mention in the Daily Prophet story about the Triwizard Tournament, whereas Harry got a whole page to himself, though this was understandable, given that Cedric was meant to be the only Hogwarts champion.
Amos was quite genial and friendly when walking through the woods with the Weasleys, Harry, and Hermione Granger. He was rather paternal, but came off as somewhat standoffish and rude due to his loud voice and boastfulness of his son's accomplishments.
He was also quite emotional, roaring with joy when discussing Cedric winning a Quidditch game and roaring with anger at Winky the house-elf when interrogating her. He sobbed openly when he saw Cedric had died and when he was interviewed about his son's death, but at least didn't blame Harry for it, and contrary, believed Harry's claim of Voldemort's return and thanked him for returning Cedric's body.
By the time Amos was an old man, he was still incredibly grief-stricken. He lamented about his "beautiful" son and had no qualms about meddling with time to bring him back. Even though he once said he didn't think Harry was responsible for Cedric's death and thanked him for bringing Cedric's body back, he changed his mind by the time he found out about a new time-turner. He thought Harry to be partly responsible since Voldemort wanted to kill him really, not Cedric. Amos would not give up until he spoke to Harry and even resolved to go round to his house to do so and angrily declared Harry to be "cold" when he would not go back in time. He was also considered a "miserable old sod" by his carers at his home.

Notes and references
- ↑ As Amos was at least seventeen years old to be working in the Ministry, and was most likely at least 17 when he became a father.
- ↑ In The Cursed Child Amos says he is "dying", but is still alive in 2020 to reveal the truth about Delphi, meaning he probably died sometime after 2020.
- ↑ As he couldn't pronounce "policemen" correctly, it is unlikely he grew up among Muggles. As well as this, the Diggory family are not included in the "Sacred Twenty Eight", which means that by 1930, they were no longer pure-blood; Amos, most likely born after 1930, would not be a pure-blood because of this. He cannot be Muggle-born due to a "Diggory" being Minister and Nobby Leech being the first Muggle-born Minister. The Diggory Minister preceded Nobby.
