Alf Erik Holger Crafoord (né Lundquist; 25 July 1908 – 21 May 1982)[1] was a Swedish industrialist and patron.

The marriage is said to have been short-lived, and Hanna Lundquist supported herself and her son in meager circumstances as the proprietor of a grocery store.

In 1961, after being unable to help two patients due to these limitations, Alwall happened to meet Crafoord at a dinner.

What Alwall needed was someone to produce disposable filters; Crafoord had experience in the manufacturing and plastics industry and was very interested in financing the product, which could save lives.

[8] In 1964, Crafoord founded the company Gambro – originally Gamla Brogatans Sjukvårdsaffär AB – which developed and three years later commercialized the invention.
