Wichmann I the Elder (also spelled Wigmann or Wichman) (died 23 April 944) was a member of the Saxon House of Billung. He was a brother of Amelung, Bishop of Verden, and Herman, Duke of Saxony.
In 938, Wichmann rebelled because his younger brother Herman had been given the military command of the northern reaches of the Duchy of Saxony. He believed that he had a better claim to the office by virtue of his seniority and because he was related by marriage to the queen dowager Matilda: that is, Königsnähe. He was joined by Eberhard of Franconia and Thankmar, the half-brother of King Otto I. The revolt was soon suppressed: Thankmar died the same year he and Eberhard came to terms. Wichmann allied with some Slavs and made war against his former compatriots. He was finally reconciled to Otto in 941.
Wichmann married Frederuna (or Fridaruna), sister of Queen Matilda. She became a nun after her husband's death and died on 18 January 971. She left hims three sons and a daughter:
See life pass you by
Your last hour growing nearer
Enjoyed all pleasures of life
trying to latch on
Desperately trying
trying to latch on
The elder want to grasp
The elder want to know
One foot in the grave
Pass on your wisdom
Made the choices and decisions
Desperately trying to latch on
See the world pass you by
Everything seems to fast
The elder want to grasp
