Guido Holzknecht

Guido Holzknecht was an Austrian radiologist who was a native of Vienna.

He studied in Strasbourg, Königsberg, and Vienna, and became the director of the X-ray laboratory at Vienna General Hospital in 1905 . He later established a central radiology department at the hospital, which became known as the Guido Holzknecht Institute. With radiologist Robert Kienböck, he was a co-founder of the Wiener Röntgengesellschaft.

The statue of Holzknecht in Arne Carlsson Park was originally made by Josef Josephu. Damaged during the Second World War, it was later restored incorrectly. The family had commissioned Josephu to show missing fingers that Holzknecht had lost due to radiation poisoning. The restored statue shows all of his fingers intact. Additionally, the signature on the restore statue read JosefHeu, who was not a sculptor - misspelling the original artists name.
