Santa Claus
Santa Claus, also known as Saint Nicholas, Kris Kringle, Father Christmas, or simply Santa, is a legendary figure originating in Western Christian culture who is said to bring gifts to the homes of well-behaved ("good" or "nice") children on Christmas Eve (24 December) and the early morning hours of Christmas Day (25 December). The modern Santa Claus grew out of traditions surrounding the historical Saint Nicholas (a fourth-century Greek bishop and gift-giver of Myra), the British figure of Father Christmas and the Dutch figure of "Sinterklaas" (himself also based on Saint Nicholas). Some maintain Santa Claus also absorbed elements of the Germanic god Wodan, who was associated with the pagan midwinter event of Yule and led the Wild Hunt, a ghostly procession through the sky.
Jenny Nyström
Jenny Eugenia Nyström (13 or 15 June 1854 in Kalmar, Sweden – 17 January 1946 in Stockholm) was a painter and illustrator who is mainly known as the person who created the Swedish image of the "jultomte" on numerous Christmas cards and magazine covers, thus linking the Swedish version of Santa Claus to the gnomes of Scandinavian folklore.
Her father was a school teacher and piano teacher, and also the cantor of the Kalmar Castle Church. When Jenny Nyström was eight years old, the family moved to Gothenburg, where her father had found a better paying teaching job.
