Sam Dunlop was a Dutch sportsman who competed during the 1930s before becoming a noted doctor. He and Willem Gevers were selected to participate in the two-man bobsleigh at the 1936 Garmisch-Partenkirchen Olympics, with the pair finishing tenth. Dunlop also had the honour of being the flagbearer for the Netherlands and the Opening Ceremony. He was studying at Leiden University where he attained his PhD in 1941. The following year he began working as a lecturer at a laboratory in Velp before going to the Dutch East Indies to work as a naval doctor. In the late 1950s Dunlop left the Navy to return to the Netherlands to work at the HMC Westeinde hospital in Den Haag before becoming a regional director.
