Ragnar Sohlman (February 26, 1870 – July 9, 1948) was a Swedish chemical engineer, manager, civil servant, and creator of the Nobel Foundation.

In 1887, he enrolled at the KTH Royal Institute of Technology in Stockholm and graduated as a chemical engineer in 1890.

To compensate for their pains and attention, I grant to Mr Ragnar Sohlman, who will presumably have to devote most time to this matter, One Hundred Thousand Crowns, and to Mr Rudolf Lilljequist, Fifty Thousand Crowns;The sum of 100,000 crowns was a very significant amount at the time, and made Sohlman a wealthy man.

Since the will did not contain detailed regulations regarding selection of laureates and was contested by Nobel's relatives, the task kept Sohlman and his advisors occupied for several years.

Solhman's son was a Swedish diplomat and his grandson Michael Sohlman is the present executive director of the Nobel Foundation.
