Leander was the second child (of 3) born to muggle parents, a lawyer and an electrician living very comfortable life in Melbourne. He liked to bake which his brother made fun of him for. Occasionally, something would go array during the process, and not always was it explainable by young Leander who would be just as confused as his parents as to how cookie dough chilling in the fridge managed to catch on fire or how the chocolate cake managed to turn out lime green when there wasn’t any food colouring in the house (and food colouring wouldn’t have masked the dark brown colour of chocolate anyway). In school Lee excelled at mathematics and did better than average in science. Teachers generally had a favourable attitude towards him for his tidy desk and careful lettering.
When it was revealed he was a wizard and required special schooling, Lee’s parents were stunned but determined sending him to a private school (Greyheme Wizarding College) was more favourable and socially acceptable than a public school, especially one with a reputation in muggle society as being a place for delinquents. Leander was glad to be away from his bully older brother and hoped that his sister would join him when it was time (she did not). At Greyheme’s Lee quickly took to potions as well as herbology, charms and muggle studies, but hated history of magic and transfiguration. The potions master at the school, a favoured mentor of Leander encouraged him to pursue extra studies after he had completed his time at Greyheme.
He followed that wisdom and chose to study in North America researching new and different potion ingredients. Coming from Australia which has very unique flora and funa, and thus atypical potion ingredients compared to other places in the world there was an adjustment period for Lee. Adjustment being code for many things blew up. It was at this time Lee learned something that had always kind of known but never quite realized: he liked experimenting in potion making. The second thing Leander learned during his time in North America was his liked teaching. Leander took extra time to finish off his studies as he decided to also take on coursework related to teaching, uncertain if he wanted to teach or be the next big potion maker when he was done.
Teaching won out in the end, with Leander deciding to move back to Australia as he missed to comfort of his birth country. A major fight with his best friend in North America also helped push him back to Australia. Just over a year ago he took a position at Tallygarunga. He hasn’t stopped experimenting, but has succeeded in only making one big potions mess in that time, at least officially. Unofficially, it’s a different story.
