Antonio Thrasybule Kébreau

Prior to his short tenure as head of state, Kébreau played a part in ousting interim president Daniel Fignolé and sending him into exile. According to Bernard Diederich in his book Papa Doc, Kébreau believed himself to be the real power behind Duvalier, as a military leader. In order to assert who really had the power, Duvalier had him sent to a diplomatic post and relieved him of his domestic duties. Kébreau took this as a threat and fled to the Dominican Republic seeking asylum, before eventually going abroad and taking up his diplomatic post.

Kébreau was appointed as the Haitian ambassador to Italy. He died suddenly on January 13, 1963. Allegedly, he was poisoned on Duvalier's orders.
