Huber studied musicology, psychology and philosophy at the University of Munich. He obtained his doctorate in 1917 and three years began teaching at the university.
In 1941 two of his students, Alexander Schmorell and Hans Scholl, who had served in the German Army on the Eastern Front, told him about the atrocities they had seen the Schutzstaffel (SS) committing in Poland and the Soviet Union. Huber responded by telling them that it was more important to overthrow the Nazi regime than the communist government in the Soviet Union.
Later that year Huber joined with Hans Scholl, Sophie Scholl, Christoph Probst, Inge Scholl, Alexander Schmorell, Willi Graf and Jugen Wittenstein to form the White Rose. The group decided to adopt the strategy of passive resistance that was being used by students fighting against racial discrimination in the United States. This included publishing leaflets calling for the restoration of democracy and social justice.
The leaflets were at first sent anonymously to people all over Germany. Taking the addresses from telephone directories, they tended to concentrate on mailing university lecturers and the owners of bars.
In Passive Resistance to National Socialism, published in 1943 the group explained the reasons why they had formed the White Rose group: "We want to try and show that everyone is in a position to contribute to the overthrow of the system. It can be done only by the cooperation of many convinced, energetic people - people who are agreed as to the means they must use. We have no great number of choices as to the means. The meaning and goal of passive resistance is to topple National Socialism, and in this struggle we must not recoil from our course, any action, whatever its nature. A victory of fascist Germany in this war would have immeasurable, frightful consequences."
The White Rose group believed that the young people of Germany had the potential to overthrow Adolf Hitler and the Nazi government. In one leaflet, Fellow Fighters in the Resistance, they wrote: "The name of Germany is dishonoured for all time if German youth does not finally rise, take revenge, smash its tormentors. Students! The German people look to us."
The White Rose group also began painting anti-Nazi slogans on the sides of houses. This included "Down With Hitler", "Hitler Mass Murderer" and "Freedom". They also painted crossed-out swastikas.
Members also began leaving piles of leaflets in public places. On 18th February, Hans Scholl and Sophie Scholl began distributing the sixth leaflet produced by the White Rose group. Jakob Schmidt, a member of the Nazi Party, saw them at the University of Munich, throwing leaflets from a window of the third floor into the courtyard below. He immediately told the Gestapo and they were both arrested. They were searched and the police found a handwritten draft of another leaflet. This they matched to a letter in Scholl's flat that had been signed by Christoph Probst.
Inge Scholl and her parents were also arrested and imprisoned. Over the next few weeks Huber, Alexander Schmorell, Willi Graf , Jugen Wittenstein and over eighty others suspected of being members of the White Rose group were taken into custody. Kurt Huber was found guilty of sedition and was executed on 13th July, 1943.
