Horace Slughorn

Professor Horace E. F. Slughorn is the current Potions Master and Head of Slytherin House at Hogwarts School of Witchcraft and Wizardry. He was Potions Professor for over fifty years and Head of Slytherin before retiring in 1981. He was a friend and colleague of Albus Dumbledore, who persuaded him to return to the post in 1996. Dumbledore enlisted the help of Harry Potter to accomplish this, together with the help of Slughorn's own fond memories of Harry's mother. He soon proved to be much kinder to Harry and a much more effective teacher than his predecessor Severus Snape had been. After retrieving a memory from Slughorn, it became apparent to both Harry and Dumbledore that the information Slughorn had provided Voldemort with led to the latter's immortality. During the Battle of Hogwarts, Slughorn sided with the Order of the Phoenix and engaged his former pupil in a duel.

It is unknown exactly when Horace Slughorn first walked into Hogwarts School of Witchcraft and Wizardry. Suffice it to say, he did so when he was eleven years old, as most young wizards in Britain do. Upon setting foot in the school and placing the Sorting Hat on his head he was sorted into Slytherin House; he soon proved to be an exceptional student, particularly gifted in the art of potion making. So much so after graduating from school, he chose to return to teach his favourite subject. At the time of Slughorn's youth, it was traditional for a young wizard, upon graduating from school, to tour the wizarding world, learning from foreign wizards. If Slughorn followed tradition, he too would likely have observed this custom before returning to Hogwarts to teach. Little else is known about Slughorn's youth except that he once took Felix Felicis when he was twenty four years old, and again at age fifty seven.

Teaching career at Hogwarts

Slughorn during the time he taught Tom Riddle.Once back at Hogwarts, Horace took on the position of Potions Master, and would eventually become Head of Slytherin House. He joined the faculty around the same time as Albus Dumbledore. Slughorn founded a small club consisting of students he thought were particularly talented, ambitious, clever, or simply well connected. This group would become known as the Slug Club. By showing extreme favouritism to these select pupils, Slughorn was able to benefit from their eventual success or fame, reaping rewards such as free Quidditch tickets, boxes of sweets, or simply the chance to give advice to high ranking officials at the Ministry of Magic.

Students he felt weren't "high-fliers," such as Arthur Weasley, and later Arthur's son Ron, he simply ignored completely. During the school year of 1944, he hosted a supper in his office consisting of a small group of Slytherin boys, most prominently among them was Tom Marvolo Riddle. After dismissing them from his study, Tom remained behind and questioned Slughorn on the matter of Horcruxes. Despite being taken aback by Riddle's interest in such Dark Magic, he reluctantly agreed to give him an overview of Horcruxes, on the condition that everything they discussed remained between them. Using the information, Riddle later went on to create seven Horcruxes, making himself immortal. The fact that Slughorn had provided the knowledge that made this possible was a terrible truth he would carry with him for the rest of his life.

Slughorn remained at Hogwarts for many years after Riddle's departure, going on to teach many talented students, including Severus Snape and Lily Evans, the latter of whom he particularly liked for her sheer cheek and natural flair for Potions. The extent of his involvement in the First Wizarding War is unknown. If, however, it was the same as the Second War, he likely went into hiding, fearing the Death Eaters would attempt to recruit him.

Retirement and life on the run

After the school year of 1981, Slughorn decided he had had enough and resigned from both his positions at the school. On 1995, he went into a secluded lifestyle, moving from one Muggle house to the next, using his many and varied contacts to maintain a very comfortable lifestyle. His reasons for doing so because he feared Voldemort would attempt to recruit him into the Death Eaters. He felt so guilty, in fact, that he modified his own memory of the incident both to hide his guilt from others and also to shield himself from the terrible shame he felt.

In an attempt to escape Dumbledore, Slughorn faked a struggle, wrecking the house and disguising himself as an armchair. He hoped Albus would be fooled into thinking the Death Eaters had kidnapped or killed him; in his haste, however, he forgot to cast the Dark Mark over the building. Dumbledore saw through this guise and forced Horace to reveal himself. Dumbledore feigned going to the bathroom, leaving Harry alone with Slughorn. Slughorn was unable to resist an opportunity to recruit the "Chosen One" into the Slug Club, and so agreed to return to the school on the condition that he received a pay raise, and was given Professor Merrythought's old office, rather than the "water closet" he had last time.

Horace Slughorn in the Great HallIn his first potions class upon returning to Hogwarts, Slughorn offered a bottle of Felix Felicis to the student who brewed the best cauldron of Draught of Living Death. Using tips scribbled in a borrowed copy of Advanced Potion Making, Harry impressed Slughorn with his attempt and won the potion. Slughorn remained impressed with Harry in class, believing that the young wizard had inherited Lily's ability in the discipline. Later that year, Dumbledore would task Harry with coercing the full memory of Slughorn's conversation with Tom Riddle from the reluctant potions master. After a disastrous first attempt in which Slughorn shouted at Harry and slammed the classroom door behind him, Slughorn became determined not to give Harry another opportunity to question him, staying out of his way in class and not inviting him to any more Slug Club suppers. Despite this, he consented to help Harry treat a love potion-struck Ron, then was spared another attempt at acquisition when Ron was subsequently poisoned by some mead Slughorn "forgot" to give Dumbledore for Christmas. Fortunately, chance and Felix Felicis gave Harry the perfect opportunit

Slughorn withdrawing his memory for Harry.One night at Hagrid's hut, to help bid farewell to Aragog, Slughorn reluctantly passed the memory about Voldemort to Harry after getting heavily drunk on wine. Harry, in turn, helped Slughorn obtain some valuable Acromantula venom from Aragog. Harry then passed the memory to Dumbledore. At the end of the school year, Dumbledore was murdered by Severus Snape. Slughorn was deeply shaken by this, commenting that he thought he knew Snape. He also expressed his concerns that parents would not allow their children to return to Hogwarts. Nevertheless, he remained at the school and resumed his old post as Head of Slytherin.[2]

The Battle of HogwartsMinerva McGonagall: "I shall expect you and the Slytherins in the Great Hall in twenty minutes, also. If you wish to leave with your students, we shall not stop you. But if any of you attempt to sabotage our resistance, or take up arms against within this castle, then, Horace, we duel to kill."
Horace Slughorn: "Minerva!"
Minerva McGonagall: "The time has come for Slytherin House to decide upon its loyalties. Go and wake your students, Horace."
— Minerva McGonagall and Horace Slughorn[src]
Slughorn stayed at Hogwarts under the tenure of Severus Snape as Headmaster and, like the rest of the teachers, attempted to protect the students from Snape and the Carrows. When the Dark Lord invaded the castle with his army, it was initially believed that Slughorn had fled in cowardice; but as it transpired, had gone to Hogsmeade to round up reinforcements. He returned to the castle at the head of vast number of residents and shopkeepers from the town, along with friends and family of the students and staff already fighting. Slughorn engaged the Dark Lord head on, with McGonagall and Kingsley, proving himself a masterful duellist, able to hold his own against even the most dangerous dark wizard of all time.[3]

Personality and traits

—Neville Longbottom talking about Horace Slughorn[src]
Horace Slughorn was described as having a bumbling, jovial sort of personality. He was rather vain and quite fond of food, especially crystallized pineapple.
Slughorn generally displayed traits of Slytherin, such as ambition. He never wished to be famous himself; instead, he preferred to help others become famous, which, if successful, gained him influence and/or benefits from them, such as being able to recommend the next junior member of the Goblin Liaison Office, free Quidditch tickets or a box of his favourite crystallized pineapple.[2]

Slughorn was keen to make evermore connections, and in his post as teacher, made a habit of having regular meetings with students who were either famous (Harry Potter), related to famous people (Cormac McLaggen), or gifted or talented in one way or another (i.e. Hermione Granger, Ginny Weasley). Known as "the Slug Club", this group of students were constantly being invited to Slughorn's office for dinner and parties.[2]

Slughorn teaching Potions to his Sixth Year N.E.W.T. classSlughorn's personality contradicts the typical "evil Slytherin" stereotype held by many Gryffindors. He is not a bad person, and has little prejudice against Muggle-born witches and wizards. However, he is horribly guilt-ridden about the information he gave to Tom Riddle about Horcruxes that helped his rise to power, and crudely edited his memory of the event to prevent anyone finding out what he'd done, and also to relieve himself of his own guilty feelings.[2]

Despite his ambition, Slughorn knew where to draw his personal boundaries. His love of powerful, talented and important people never blinded him to his moral values, and thus, he was never tempted to join forces with Lord Voldemort and his Death Eaters. Unlike Peter Pettigrew and other characters who were keen to surround themselves with big people, he was not one to side with whoever was winning. Slughorn knew where his loyalties were, as he fought against Lord Voldemort during the final battle.

— Albus Dumbledore and Horace Slughorn[src]
Slughorn has prominent, pale gooseberry coloured eyes, a shiny pate, and an enormous, silver, moustache that looked like a walrus'. (though in the movie, this is ommited due to Jim Broadbent's dislike of wearing moustaches), which in his youth was gingery blond and his hair was thick and straw coloured. He is short and round, and claims to suffer from old age, rheumatism and a weak chest.

However, he is still sufficiently agile to turn himself into an armchair and create a scene of chaos at short notice when he is trying to avoid unwelcome visitors, and managed to live on the run from Voldemort moving house every couple of weeks (including his grand piano). He has a liking for embroidered clothing, with gold coloured buttons and plenty of velvet. [2]

Horace Slughorn was an uncommonly powerful wizard, with a wide variety of skills.

Occlumency: Horace was an extremely able Occlumens, being able to shield his mind against even a wizard of Albus Dumbledore's calibre. He has mastered his mind to the point of being able to modify his own memory to make it seem something less horrible, as seen with the memory about Tom Riddle asking about Horcruxes. However, this was crudely done, as parts of the memory were clouds, rather than actual visual.

Master Duelist: Slughorn was a master duelist, being able to hold his own against even Lord Voldemort himself; the fact that Voldemort was wielding the Elder Wand during that duel is further evidence of Slughorn's amazing ability (although Voldemort had failed to unlock the Elder Wand's power at the time).[3]

Master Potioneer: Perhaps chiefly among Slughorn's many talents is his ability as a potioneer. Slughorn was able to create extremely complicated Potions such as Felix Felicis, Polyjuice Potion and Amortentia. He is an expert on Potions, as he teaches the subject up to N.E.W.T. level, and is seen to be an equal to Severus Snape in the subject as he understands and agree's with Snape's edits in a copy of Advanced Potion Making.[2]

Memory Modification: Horace Slughorn possibly used some form of the False Memory Charm to rework the memory of his discussion with Tom Riddle about the nature of Horcruxes. Professor Dumbledore, however, commented that the alterations were "very crudely done".
