World War I brought this heyday to an abrupt end as foreign patients stayed away for years. From 1926, Dr Oscar Ullmann was in charge of the spa institution with his eldest son, Dr Waldemar Ullmann, who took over from him in 1935. World War II and the institution’s close proximity to Germany triggered a serious crisis.
NURTURING A FAMILY TRADITION. FROM A HEALTH SPA TO A LEADING PRIVATE CLINIC.
AFTER THE SECULARISATION, SCHLOSS MAMMERN, BUILT IN 1621, WAS CONVERTED UNDER VARIOUS OWNERS INTO A HYDROTHERAPY SPA. IT WAS THE YOUNG DR OSCAR ULLMANN WHO SUCCEEDED IN TURNING THE AILING SPA INSTITUTION INTO A FLOURISHING INTERNATIONAL INSTITUTION IN 1889. THE ENSUING GENERATIONS CARRIED THIS DEVELOPMENT FORWARD UP TO THE PRESENT DAY.
Dr Waldemar Ullmann died childless on 14 September 1944 and it was his sister Ilse Fleisch-Ullmann who assumed the reins of the spa institution together with her husband Professor Alfred Fleisch. From 1958, their son Dr Alfred Oscar Fleisch, cardiologist, was the medical and administrative director. This marked the beginning of a highly successful development.
In 1997 Dr Alfred Oscar Fleisch handed over the medical direction to his daughter Dr Annemarie Fleisch Marx and his daughter-in-law Dr Ruth Fleisch-Silvestri. The two Chief Physicians have successfully managed the clinic and its more than 270 employees, with the support of its Director Beat Oehrli, up to the present day.
