He left that family surgical supply business in 1895 to found what became Mead Johnson, which produces nutrition products for infants and children marketed in fifty countries around the world.
[1] In 1895, Johnson developed a side business, The American Ferment Company, to create a digestive aid.
The firm moved to Evansville, Indiana, in 1915, as part of an effort to have easier access to the raw agricultural ingredients that were needed for its products.
The relocation required Johnson to build a series of new plants and factories to replace the facilities he had left behind in New Jersey.
[3] Johnson died at age 81 on March 20, 1934 of a heart attack suffered at his winter home in Miami Beach, Florida.
