Władysław Tryliński

Władysław Tryliński (20 June 1878 – 6 February 1956) was a Polish transportation engineer and inventor. He is best known for the creation of ''trylinka'', the hexagonal concrete block widely used for pavements and embankments in interwar Poland, and the engineering design of the Maurzyce Bridge, the world's first entirely welded road bridge—developed in collaboration with construction engineer Stefan Bryła.

In recognition of his contributions, Tryliński was awarded the Officer's Cross of the Order of Polonia Restituta, Poland's second-highest civilian state award, in 1923, and the Gold Cross of Merit in 1939. Provided by Wikipedia
