Charles and the children were officially Swiss nationals until they became [[naturalised]] on 22 October 1919.<ref>{{harvnb|Farmelo|2009|p=34}}</ref> Dirac's father was strict and authoritarian, although he disapproved of corporal punishment.<ref>{{harvnb|Farmelo|2009|p=22}}</ref> Dirac had a strained relationship with his father, so much so that after his father's death, Dirac wrote, "I feel much freer now, and I am my own man." Charles forced his children to speak to him only in French so that they might learn the language. When Dirac found that he could not express what he wanted to say in French, he chose to remain silent.<ref>{{harvnb|Mehra|1972|p=17}}</ref><ref>{{harvnb|Kragh|1990|p=2}}</ref>
