Heinrichs Skuja

Heinrichs Leonhards Skuja (Latvian: Heinrihs Skuja; 8 September 1892 – 19 July 1972) was a Latvian phycologist active in the 20th century. He is considered an outstanding phycologist and protistologist of his time.

Skuja was actively involved in the study of Latvian algae beginning in 1924. After escaping to Sweden in 1944 near the end of World War II, he continued researching algal systematics and ecology in Uppsala. He received several academic awards from both countries for his contributions to phycology. Due to his extensive knowledge of algae, he received samples from scientific expeditions around the world to be identified by him. He described thousands of new taxa and published over 70 papers and monographs that were accompanied by his own scientific illustrations. In his private life, he invested time in art and music, and was well-regarded by his friends and colleagues.
