My husband, Brian Seller, who has died aged 68 of cancer, was a chartered civil engineer who worked for London Underground for more than 30 years and by retirement had become one of its of principal engineers, working on a large number of projects, including the tube tunnel extension to Heathrow Terminal 4. He particularly enjoyed being involved with the graduate trainee scheme and mentoring young engineers towards chartership.
Born in Kirkcaldy in Fife, Brian was the youngest son of Jane (nee Twiby), a homemaker, and her husband, John Seller, who was in the army. When his father’s work took the family to Coulsdon in Surrey, Brian attended Chipstead Valley school, where he met Christopher Murphy, who became his lifelong friend. The alliance between the two initially formed because their mothers insisted they should start secondary school wearing short trousers.
