Seven generations of the family of Vilmorin contributed greatly to French agriculture for over two hundred and thirty years by their improvements of sugar-beet and wheat - they published more than three hundred and sixty articles on plants in agriculture, horticulture, floriculture and botany.
Henry's great-grandfather Philippe Victoire de Vilmorin 1746-1804 and "his" wife's father, Pierre Andrieux, chief seed supplier and botanist to King Louis XV, revived an old seed-growing firm and named it Vilmorin-Andrieux in 1774.
Henry headed the firm from 1873 and was the first to hybridise wheat.
As a result, he introduced 18 strains of high-yield wheat while continuing his father’s work on the breeding of sugar beets, and publishing "Les meilleurs blés" ('The Best Wheat') in 1880 with descriptions of the best winter and spring wheat varieties and their cultivation.
This was followed by a supplement published by "Vilmorin-Andrieux et Cie" in 1909.
He also produced a small book "Flowers of the French Riviera" in 1893.
Hooker dedicated the 125th volume of "Curtis's Botanical Magazine" to him.
