[1] He had no formal academic or scientific training (although he had attended some lectures by Hans Christian Ørsted).

In the 1840s, he had come to realise that production of beer, which had until then been done in numerous small breweries, now had to be based on the scientific method in order to be industrialized.

Starting in 1847, he established his brewery Carlsberg in Valby on the outskirts of Copenhagen, on a site where it has remained since.

Being extremely vigorous in the pursuit of producing high quality beer, he founded the Carlsberg Laboratory[2] in 1875.

It is now housed in the Ny Carlsberg Glyptotek, a museum founded by him in Copenhagen.
