Tiberius Zeller was once one of the most powerful men in the Ministry of Magic. The Head of his department, he was close friends with the murdered Minister Scrimgeour. Hermione remembered Cormac McLaggen mentioning his uncle's close friendship with the Head of their government. It had been impressive enough to earn him a spot in the coveted Slug Club. One of the few who actually survived a Ministry purge with his life intact, Tiberius might've disappeared into obscurity if it hadn't been for the tragedy that befell his only daughter Rose ten years after the war ended.
