Klaus Kinski was renowned for his crazed, insane behaviour both on & off the screen. What is perhaps not so well known is that in 1950 he was admitted to a psychiatric hospital, where a presumptive diagnosis of schizophrenia was made. No information is available on what sort of treatment he received. His work opportunities dried up after that time, culminating in 2x suicide attempts in 1955. Again, little information is available on what exactly occurred.
The only person to attend Klaus Kinski's funeral in 1991 was his beloved son, Nikolai. Kinski was cremated & his ashes scattered in the Pacific.
