Christian Harald Lauritz Peter Emil Bohr (1855–1911) was a Danish physician, father of the physicist and Nobel laureate Niels Bohr, as well as the mathematician and football player Harald Bohr and grandfather of another physicist and nobel laureate Aage Bohr. He married Ellen Adler in 1881.

Personal life

He wrote his first scientific paper, "Om salicylsyrens indflydelse på kødfordøjelsen" ("On salicylic acid's influence on the digestion of meat"), at the age of 22. He received his medical degree in 1880, studied under Carl Ludwig at University of Leipzig, took a Ph.D. in physiology and was appointed professor of physiology at the University of Copenhagen in 1886.[4]

On his religious views, Bohr was raised as a Lutheran. He was an atheist in later life.[5]

Christian Bohr is buried in the Assistens Kirkegård.


In 1891, he was the first to characterize dead space.[6][7]

In 1903, Christian Bohr described the phenomenon, now called the Bohr effect, whereby hydrogen ions and carbon dioxide heterotopically decrease hemoglobin's oxygen-binding affinity. This regulation increases the efficiency of oxygen release by hemoglobin in tissues, like active muscle tissue, where rapid metabolization has produced relatively high concentrations of hydrogen ions and carbon dioxide.

As for standard religion, though, Bohr was unsympathetic. His mother was a nonpracticing Jew, his father an atheist Lutheran.
