Roots of the business go back to the 19th century, with meetings & congresses in Davos. Even then, famous guests and doctors from across Europe were living in Kurort. They shared their expertise at congresses. 1923, Davos doctors organised the first international congress. Albert Einstein opened the first "university course in Davos in 1928". This elevated Davos to the status of a congress city and it began to be recognised as a meeting point for the intellectual elite.
