Johan Sigfrid Sirén
Finnish architect (1889–1961)

Johan Sigfrid Sirén (27 May 1889 – 5 March 1961) was a Finnish architect. He is best known for Parliament House, which is where the Parliament of Finland meets.
Career
Sirén was born in 1889 in Ylihärmä. In 1907, he graduated from high school and started his studies at the Helsinki University of Technology. After receiving his diploma in 1913, Sirén worked for Jung & Fabritius until 1917. In 1918, he founded an office with Kaarlo Borg and Urho Åberg. In 1924, they won a contest for the design of the Parliament House of Finland. The three soon parted ways and Sirén continued work on the Parliament House alone. During the construction period from 1926 to 1931, he acted as a supervisor.
Sirén went on to hold his own office, and his later work included the expansion of the main building of the University of Helsinki.

Why this record matters
“Johan Sigfrid Sirén” is worth following because a concise public description often conceals a longer documentary argument. Here, Johan, Sigfrid and Sirén provides the most credible route into that argument.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Nov 24, 2024. The linked authority identifier is Q499284. VIAF identifies the subject as 15569557. The Library of Congress control number is n90719665. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1889, 1961, 1907 and 1913.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
