Algie Longbottom

Algie Longbottom is a pure-blood wizard, the paternal uncle of Frank Longbottom and thus the great-uncle of Neville Longbottom.

Neville's family initially believed he might be a Squib, but Algie was determined to catch Neville off his guard and "force some magic" from him. He once pushed Neville off the end of Blackpool Pier, but the boy nearly drowned. When Neville was eight, Algie accidently dropped him from an upstairs window, and the boy bounced, proving that he was in fact a wizard.

It was Algie who gave Neville his pet toad Trevor, as a "reward" for gaining entrance into Hogwarts, and his Mimbulus Mimbletonia plant.

Behind the Scenes
Algie is a short form of the name Algernon, originally a Norman French name derived from aux gernons, meaning “having a moustache”. This is the name of a main character in Oscar Wilde’s The Importance of Being Earnest. Algie is also a homophone of the plant-like organisms algae, possibly referring to the interest in Herbology that Algie and his great-nephew seem to share.
