About:

Helga Hufflepuff (fl. c. 993) was a Welsh witch and was one of the four founders of Hogwarts School of Witchcraft and Wizardry. While the other founders chose to have special students, she accepted them all without preference, but the students of her house are described as loyal and hard-working. Helga's portrait remains at Hogwarts. United by the common goal of creating the world's best magic school, Helga Hufflepuff, and her good friends Rowena Ravenclaw, Godric Gryffindor, and Salazar Slytherin built Hogwarts Castle together and established Hogwarts School of Witchcraft and Wizardry sometime around 993. She brought people from different backgrounds together to help in the building of the school. While the other founders took students based on either ambition, bravery, or intelligence, Helga took the loyal, hard-working, patient and tolerant and treated them all equally. She had a gift for Food-related charms, and her recipes are still used as the basis for many Hogwarts feasts. She also arranged for the house-elf contingent to work in the kitchens, giving them somewhere safe to work, where they would not be mistreated or abused.
Helga favoured loyalty, honesty, fair play, and hard work, but was known to accept all students regardless of whether or not they possessed these traits. Members of her House usually display at least one of these traits in varying degrees. Given that all of her portraits show her with a wide smile, it can be inferred that Helga was a very jolly woman. Her affinity for food-related charms and plump shape might also indicate that she had a large appetite. She was also a woman of tolerance, willing to accept Muggle-born students and disagreed with Slytherin's pure-blood exclusiveness, as well as bringing together people of varying backgrounds to construct the school and ensuring a decent working environment for house-elves, who were generally treated with indifference if not outright cruelty by most wizards.
The name Helga is from Helge, from Old Norse heilagr, meaning "holy" or "blessed". Their symbol is the badger, a large mammal related to the weasels with distinctive white stripes on its head. In Celtic mythology, a badger was a guide. The badger also can symbolise a tendency to be hard-working, strong, and tenacious. Hufflepuffs are known for loyalty and hard work. Helga was a name which was common in northern Europe; in countries such as Norway. It was soon adopted by many soviet countries and others which bordered with the north, including; Russia, Latvia, Denmark and Belgium. As those in northern Europe pronounced the 'e' in Helga as more of a cross between 'e' and 'o', and, like the french, didn't pronounce the 'h', the soviet countries adopted the name as 'Olga'. Some countries, including Germany, kept the name as 'Helga'. Hufflepuff could mean "huff and puff" or blustery. "Huff" also means to breathe; "puff" is a medieval term for pastry.
