From a documentary about Ferdinand:
They said something interesting about Ferdinand's father, August of Saxe-Coburg and Gotta. Until his death Ferdinand forbade anyone to even mention his father, because he was ashamed that August has spent the last days \years?\ of his life in a psychiatry. I couldn't find more info on that subject online \about August\. Could it be true?
And these are from Maria Luisa's short biography that I bought today.
