Later he worked in close association with the great physiologist F.C. Koster, and was entitled “Quelques remarques sur le mécanisme de l’articulation du coude” (Some remarks on the elbow joint).

The first was carried out after Einthoven had gained his “candidaat” diploma (approximately equivalent to the B.Sc. in the renowned eye-hospital “Gasthuis voor Ooglidders”, he made two investigations, both of which attracted widespread interest.
