Between 1859 and 1869, Albrecht von Graefe used to spend some weeks in September in Heiden, a small health resort in Eastern Switzerland. During his "holidays", however, the hotel "Freihof", where he lived, was transformed into a most active unit of ophthalmic surgery. A memorial stone, rediscovered and restored thanks to the endeavour of Professor Peter Speiser of St. Gallen, remembers this episode, which was of some importance not only for local tourism, but also for the young Swiss ophthalmology of the time.
1859年至1869年间，阿尔布雷希特·冯·格拉费每年9月都会在瑞士东部的一个小疗养地海登待上几周。然而，在他“度假”期间，他所居住的“弗里霍夫”酒店变成了一个极其活跃的眼科手术单位。多亏了圣加仑的彼得·施佩泽教授的努力，一块重新发现并修复的纪念石铭记了这一事件，这一事件不仅对当地旅游业很重要，对当时年轻的瑞士眼科学也具有一定意义。
