One example of the early western influence in Korea is the Pai Chai Institute which has ben established in 1885 by the American missionary Appenzeller (which must have had Swiss roots for sure).
Visit Seoul seems to be the best source to get information about the Appenzeller Noble Memorial Museum if you don’t speak Korean.

Unfortunately also the Facebook page is completely in Korean: Facebook-Page
