Holger F. Struer was a Danish physicist. He was born in Copenhagen in 1904 and died in 1978. He studied mathematics, physics and electrical engineering at the Technical University of Denmark, and he received his PhD in 1932. He was a professor at the same university from 1937 to 1974.
Holger is most known for his work in the field of X-ray physics, which is the study of how X-rays interact with matter. He developed a range of X-ray instruments used to examine the internal structure of delicate materials, like those used in medical imaging. His X-ray instruments helped make medical imaging more accurate and detailed. He also worked with nuclear physics, including the development of new methods for measuring the age of rocks.
Holger's impact on science was significant; he developed instruments and methods that are still used today. He also published several books which are still used by students and researchers. Holger was a respected scientist, and he received several awards in recognition of his work.
