Adrianus Cyriacus Bleijs, sometimes incorrectly spelled Bleys, was born in Hoorn in 1842 as the son of a carpenter. He received his education as an architect at the Royal Arts Academy in Antwerpen, Belgium, where he graduated in 1864, after which he worked at the office of P.J.H. Cuypers for a while as a drawer. A disagreement with his boss got him fired, after which he set up his own office in Hoorn.
Bleijs was one of only a few catholic architects who did not totally comply to the neo-Gothic standard for catholic churches. Although he built several neo-Gothic churches he became best known for churches in other styles. Some are neo-Romanesque style, others are neo-Renaissance, a style that was typical for protestant churches at that time, not for catholic ones. Besides churches, of which he built fourteen, he designed numerous other buildings, including two hospitals in Amsterdam.
In 1903 Bleijs quit architecture and became a civil servant in 's-Hertogenbosch. He died in Kerkdriel in 1912.
