What was used before Zyklon B?

In early 1942, Zyklon B emerged as the preferred killing tool of Nazi Germany for use in extermination camps during the Holocaust. The chemical was used to kill roughly one million people in gas chambers installed in extermination camps at Auschwitz-Birkenau, Majdanek, and elsewhere.

Similarly, it is asked, which extermination camp killed the most?
