What was it like for Elie Wiesel after the war?

In 1945, Jewish man Elie Wiesel was liberated from the Buchenwald concentration camp.  He did not let his traumatizing concentration camp experiences keep him from living an active life.  He was a man with many accomplishments.  His hardships inspired him to help others and advocate for them.  
After the war, Wiesel went to France to study.  He took an interest in journalism.  He wrote a memoir about his experiences in the concentration camp.  The memoir was in Yiddish.  He shortened the memoir and released it as La Nuit in France.  In English, the book was simply called Night.  This is his most popular work.  He wrote many other books, as well.
In the 1950s, Wiesel immigrated to the United States.  He met and married Marion Rose, who was also a Holocaust survivor.  Together, they had a son.
Wiesel became an activist.  He gave many speeches about peace in times of violence and turmoil.  His views and his activism were based based on his traumatizing experiences as a Jewish man living under Nazism.
Wiesel was awarded the Presidential Medal of Freedom.  In 1986, he was awarded the Nobel Peace Prize.  In his later years, he became a college professor.
