Nope...neither Ottor nor his four brothers were physicians...they studied law and economics and married late, therefore insuring that children would arrive after they had settled into profitable careers. Rudolf and Carl Ludwig lived mostly in Belgium, while Felix settled in Mexico, where several of his children continue residing. Robert spent quite some time managing the estates inherited by his wife, Margherita of Savoy, and also had a successful career as a businessman...he was the most Parma-looking of Zita and karl's boys.
Archduke Otto is a prolific writer in history, economics and politics, and had a tremendously successful political career, both in the European parliament and as president of the Pan-Europa movement.
