Jean de Neuflize

Jean Frédéric André Poupart, 4th Baron of Neuflize CVO (21 August 1850 – 20 September 1928) was a French banker and equestrian. He received recognition with his appointment as an officer of the Legion of Honour.

Early life
Neuflize was born in Paris on 21 August 1850 into the prominent minority Protestant establishment of France. He was the eldest son of Jean André Poupart de Neuflize, 3rd Baron of Neuflize (1820–1868), and his wife, Marie Louise André (1826–1907).

His great-grandfather, Jean Abraham Poupart de Neuflize (who was made the first Baron of Neuflize in 1810), built the Château de Montvillers in 1770 in Bazeilles in the Grand Est region of northern France.

He was educated at the Lycée Saint-Louis, followed by the Lycée Bonaparte.

Career
Neuflize, a banker, succeeded his father as the head of the Banque de Neuflize et Cie in Paris, which had been founded in 1710 by his great-grandfather Jean Abraham Poupart de Neuflize, a draper from Sedan, Ardennes, and traced its lineage to seventeenth century Genoa. His family's bank was among the most prominent banking houses of France, which included the Hottinguer, Mallet, Rothschilds and Vernes banks. He was succeeded in the bank by his second son, Jacques, who was the representative of the Banque de French in America during World War I.

From 1902 until his death in 1928, he was a Regent of Banque de France, the central bank of France, and was serving as Dean of Regents at the time of his death. In 1904, he helped established the French investment bank Banque de l'Union Parisienne. He was also vice president of Paris, Lyons & Marseilles Railway, chairman of the board of directors of the Ottoman Bank, and president of the Évian Mineral Water Society.

Equestrian
In June 1900, Neuflize was awarded third place in the four-in-hand (mail coach) driving event during the International Horse Show in Paris. The show was part of the Exposition Universelle, and the equestrian events were later classified as part of the 1900 Summer Olympics.

She was born in Soisy-sous-Montmorency and was a daughter of Mathieu Dollfus and Laure Cécile Davillier, and granddaughter of industrialist Jean Dollfus. In Paris, they lived at 7 Rue Alfred-de-Vigny, a Hôtel particulier in the 8th arrondissement, Together, they were the parents of three children:
