Ann Maguire was born in 1953 and grew up in Leeds. She studied at Trinity and All Saints College and joined Corpus Christi as a young teacher in 1974, the year the school opened. She stayed for four decades. She taught Spanish, ran the school's pastoral programme, organised foreign exchanges, helped at every school production, knew the family circumstances of children whose parents could barely manage to send them in uniform. Children who passed through her classes describe a teacher who remembered them. She and her husband Don raised four daughters in the same Leeds suburb. By the time of her death she had grandchildren. Pope Francis sent condolences to her family. Her funeral was held at the Roman Catholic church where she had worshipped most of her life, and where she had once sung in the choir.

She arrived at school as usual that Monday. After morning break she walked up to the top floor for her Spanish lesson with Year 11s - the pupils she had taught since their first day at the school nearly five years earlier. The attack came halfway through. Susan Francis, the Head of Languages, heard screaming from the corridor and ran. She put herself between Ann Maguire and the attacker, separated them, got Ann into another room and held the door shut to keep him out. The actions Susan Francis took in those moments, by every available account, were extraordinary. Ann Maguire was rushed to Leeds General Infirmary. She did not survive.

Corpus Christi Catholic College sits in Halton Moor, a post-war Leeds council estate east of the city centre. It opened in 1974 as a Roman Catholic comprehensive secondary, drawing students from the eastern parishes. Ann Maguire arrived as part of that founding generation of staff. Her presence shaped the school. Even visitors who never knew her, walking the corridors in the weeks after her death, described banks of flowers, hand-written notes from former students stretching back to the 1970s, framed photographs in the corridor. The Spanish department named its annual award after her. Members of the school community asked, again and again, for an inquest - which was eventually held in November 2017.

The inquest was supported by Ann Maguire's family and resisted by West Yorkshire Police, by the school, and by Leeds City Council. Its verdict, returned in November 2017, was that opportunities to prevent her murder had been missed. The inquest found that other pupils had heard the perpetrator discuss harming Ann Maguire in advance, and had seen the knife at school, and had not reported either to staff. It questioned why teachers and parents had not picked up on warning signs in the months before. The Maguire family pressed the issue not for retribution but to ensure another teacher would not die the way Ann had. After the verdict, her family - Don, their daughters, her sisters and brothers - continued to campaign for better safeguarding, for reporting cultures within schools, for better recognition of staff who teach in difficult environments.

Ann Maguire was the first teacher killed by a pupil in a British classroom in modern memory. The fact alone gave the case a brutal singularity. But the family and former pupils have resisted letting that singularity define her. She is remembered at Corpus Christi by the prize named for her, by an annual mass in her memory, by the trees planted in the school grounds. Memorial plaques exist in churches and community halls across east Leeds. The Pope mentioned her at a Vatican audience. Former pupils, now in their thirties and forties, have spoken publicly about wanting Ann remembered for the forty years of teaching, not the day she died. A teacher of forty years is many thousand quiet good acts - parents' evenings, exam concerns smoothed over, encouraging words to children whose lives at home were uncertain. That is the woman her family asks visitors to Leeds to remember.
