Paul Gibier (October 9, 1851–June 23, 1900) was a French medical doctor and bacteriologist, a researcher into contagious diseases, who founded the New York Pasteur Institute.

[4] In 1887 Gibier published Le spiritisme (fakirisme occidental), a critical and experimental study that included discussion of mediums, North American Indians and Hindu Fakirs.

[5] In this book, in which he claimed to be scientifically impartial and apparently reported experiments objectively, he indulged in violently anti-Catholic views.

[6] In 1889 Gibier published his Physiologie transcendantale: Analyse des choses in which he described his research into psychological physiology, including careful studies of hypnotism, telepathy, duplication and so on.

[3] He hoped to find the yellow fever microbe that had been reported by Dr. Domingos José Freire of the Rio de Janeiro faculty of medicine.

[3] The institute, headed by Paul Gibier and with Dr. C. Van Schaick as assistant and Dr. A. Liautard as consulting veterinarian, opened on 18 February 1890.

[11] This quarterly journal, later renamed the Bulletin of the New York Pasteur Institute, included accounts of studies by Gibier and his colleagues, translations of medical articles from French and German, reports on rabies treatments, and advertisements for medical devices and products for practitioners, including antitoxins and serum remedies.

[13] Writing in the North American review Gibier advanced the view that the medical "priest" should lead the movement from "sentimental" to "scientific" religion.

He thought that only the doctor could diagnose diseases such as socialism and anarchy, and that with his knowledge of genetics he could "contribute to the purification of the race" through marriage counseling.
