Names : Frank and Alice Longbottom
General : the parents of Neville Longbottom, a Gryffindor boy in the same year as Harry Potter at Hogwarts. Along with Alastor Moody, they are remembered as being three of the greatest Aurors the Ministry ever had. According to Dumbledore, they had "thrice defied" Lord Voldemort by 1981.
Their success, however, was cut short, as Frank and Alice were tortured into insanity with the Cruciatus Curse by a group of Death Eaters, led by Bellatrix and Rodolphus Lestrange, and which included Bartemius Crouch Jr. Neville was raised by his paternal grandmother while his parents became permanently resident in a Closed Ward at St. Mungo's Hospital for Magical Maladies and Injuries. Their torture is remembered by the Order as one of the most horrific crimes committed by Voldemort's followers.
Neville and his grandmother visit Frank and Alice over the holidays. Neither of them recognize him as their son, but Alice rather recognises Neville as someone she likes. In Harry Potter and the Order of the Phoenix, Alice gives Neville a Droobles bubble gum wrapper during his visit at Christmas break and Neville puts it in his pocket even though his grandmother tells him to throw it away, saying that he already has many others. The significance of this incident was hotly debated by fans, but this debate has recently been put to rest in an interview with author J.K. Rowling, in which she stated the event has no further implications towards the plot of the story, but was merely based on events of a friend and his mother with Alzheimer's.
Frank's wand was used by Neville while he attended Hogwarts, until it was broken in Order of the Phoenix in the Department of Mysteries in the Ministry of Magic, by the Death Eater Antonin Dolohov.
