"Bo Lindgren was the son of Fritjof Lindgren (see February 23rd). International Judge since 1966 and Grand Master since 1980, he was the editor of the problem columns of Skakbladet from 1952 until 1957 and collaborated with Stella Polaris from 1966 until 1970.
A collection of 197 of his best problems was published in 1978 by Walther Jørgensen, titled "Maskrosor" (Dandelions).

John Rice wrote an inspiring two-part article "The Lindgren Legacy" selecting 52 of Lindgren's problems in The Problemist November 2011 and January 2012: a worthy homage to the Swedish GM. The problems below were also quoted by John Rice."

 "With his passing, not only Sweden but the entire problem world has lost an outstanding personality. Until a few years ago, Bo was a regular visitor to the PCCC meetings, and he was also a frequent guest at the Andernach meeting until health problems prevented him from travelling a few years ago."
