Jules-Pierre Mao is the owner of Mao-Kwikowski Mercantile as well as its subsidiary Protogen. One of his daughters, Julie Mao, was affiliated with the OPA.
His aforementioned business interests are implicated in unethical research and commercialization of the protomolecule. He was demonstrated to have colluded and allied with UN Undersecretary Sadavir Errinwright to hide the project.
Mao was born on Earth on an undisclosed year. Due to his accent and name, he is thought to be of a combination of Chinese and French heritage.
He has two daughters, Clarissa and Julie, and two sons. He also has a cousin who is a monk.
In "The Big Empty" , Jules-Pierre Mao is seen in an old video message to Julie, telling her to come home. Julie effectively refuses thereafter and denies further manipulation from her father.In "Critical Mass" , Dresden reports to Mao that Julie is dead, and that they must move forward using Mao's deceased daughter as a sacrifice and let the protomolecule absorb her consciousness. Jules-Pierre agrees and gives the order to proceed. In "Leviathan Wakes", the United Nations Secretary-General, Esteban Sorrento-Gillis, convenes a meeting with security contractors, to which Jules-Pierre Mao is summoned.
