He owned a fleet of oil tankers and other vessels and became known for his lavish lifestyle, private island, luxurious yacht, and influential social connections. In 1946, Aristotle Onassis married Athina Livanos, the daughter of the wealthy Greek shipping magnate Stavros Livanos.Their marriage brought together two influential Greek shipping families. Athina was young, elegant, and part of a prominent business dynasty.
Despite their wealth and privileged lifestyle, their marriage experienced difficulties. Onassis’s business commitments, personal relationships, and reported infidelities contributed to marital tensions. The couple eventually divorced in 1960. Their separation marked the end of their marriage, but their family remained connected through their children.. One of the most famous relationships in Onassis’s life was with Maria Callas , the celebrated Greek-American opera singer. Their relationship began in the late 1950s, when both were already internationally famous. Callas was married to Giovanni Battista Meneghini when she met Onassis, while Onassis was still married to Athina Livanos.
