This page is about the Book-icon-simple books character. For the TV incarnation, see Jules-Pierre Mao (TV).

Jules-Pierre Mao is one of the owners of Mao-Kwikowski Mercantile, and also owns shares in Star Helix Security. He is the husband of Ariadne Mao, and together they had several children: Juliette AndromedaClarissa Melpomene, Petyr, and twins Michael and Anthea.


Mao is a handsome man with startling blue eyes. Middle-aged, he has a receding hairline that he chooses not to modify by medical therapies, giving him a dignified look.


He operates out of Mao Station in Luna's orbit, and has his own yacht, the Guanshiyin.

Eros IncidentEdit

Because his company was one of Protogen's major suppliers prior to the Eros incident, Mao and his wife were eager to recover their daughter Julie, who had become estranged and left Luna for the Belt to join the OPA, to save her from the war. Mao used his power and status as a shareholder in Star Helix Security to make them find her, kidnap her and send her back to Mao Station. This job fell on Captain Shaddid, head of the police force on Ceres, where Julie lived. She put Detective Miller on the case, who was ultimately unsuccessful.

During the aftermath of the Eros incident, Mao and his company argued they didn't know what their equipment was used for, and no evidence was found to implicate them.

Ganymede IncidentEdit

After the Ganymede incident Jules-Pierre has a meeting with the United Nations Assistant Undersecretary of Executive Administration, Chrisjen Avasarala. During the meeting Avasarala tries to pry any information about Venus he may have left out of the hearings of Protogen but he denies giving a calm sense of professionalism.

After Jim Holden discovered that the United Nations worked with Mao-Kwikowski Mercantile in creating the human-protomolecule hybrids, Mao was convicted and sent to prison.

The RingEdit

His daughter Clarissa Mao vowed to avenge him by destroying Holden.
