Haase was born in Köthen, in Anhalt. He obtained his Doctor's degree in 1924 and then became a surgeon. He joined the Nazi Party in 1933. From 1934, forward, he served on the staff of the surgery clinic of Berlin University.
In 1935, he began serving as Hitler's deputy personal physician. On 1 April 1941, Haase joined the SS. He was promoted to SS-Obersturmbannführer on 16 June 1943. Hitler appears to have had a high opinion of him. The book Hitler's Death: Russia's Last Great Secret from the Files of the KGB, based on documents in the Soviet archives, reproduces a telegram from Hitler sent to Haase on his birthday in 1943, stating: "Accept my heartfelt congratulations on your birthday."
In the last days of the fighting in Berlin in late April 1945, Haase, with Ernst Günther Schenck, was working to save the lives of the many wounded German soldiers and civilians in an emergency casualty station located in the large cellar of the Reich Chancellery. The cellar led a further one-and-a-half meters down to an air-raid shelter known as the Vorbunker. The Vorbunker was connected by a stairway which led down to the Führerbunker. By this time, the Führerbunker had become a de facto Führer Headquarters, and ultimately, the last of Hitler's headquarters.
In addition, Hitler's personal physician Theodor Morell and several others were ordered to leave Berlin by aircraft for the Obersalzberg. When Morell left Berlin on 23 April, he left behind prepared medicine; during the last week of Hitler's life, it was administered by Dr. Haase and by Heinz Linge, Hitler's valet. On 29 April, Hitler expressed doubts about the cyanide capsules he had received through Heinrich Himmler's SS. To verify the capsules' potency, Haase was summoned to the Führerbunker to test one on Hitler's dog Blondi. A cyanide capsule was crushed in the mouth of the dog, which died as a result. Hitler in conversations with Haase during this timeframe, asked the doctor for a recommended method of suicide. Haase instructed Hitler to bite down on a cyanide capsule while shooting himself in the head. He remained in the Führerbunker until Hitler's suicide the following afternoon. Haase then returned to his work at the emergency casualty station. Haase, Helmut Kunz and two nurses, Erna Flegel and Liselotte Chervinska were captured there by Soviet Red Army troops on 2 May.
On 6 May, Haase was one of those taken by the Soviet authorities to identify the bodies of the former Reich Propaganda Minister and (for one day) Reich Chancellor, Joseph Goebbels, his wife Magda Goebbels and their six children. Haase identified Goebbels' body, despite it being partly burned, by the metal brace which Goebbels wore on his deformed right leg.
Haase was made a Soviet prisoner of war. In June 1945 he was charged with being "a personal doctor of the former Reichschancellor of Germany, Hitler, and also treated other leaders of Hitler's government and of the Nazi Party and members of Hitler's SS guard". The sentence is not recorded. Haase, who suffered from tuberculosis, died in captivity in 1950. The place of death is recorded as "Butyr prison hospital". This is probably a reference to the Butyrka prison in Moscow.
