Augustus Carfrae was a notable Scottish engineer and inventor, recognized for his contributions to the field of civil engineering during the 19th century. He is best known for his work on the design and construction of bridges, particularly the innovative use of wrought iron in bridge building, which significantly advanced engineering practices of the time. Carfrae's most famous project is the Forth Bridge, a cantilever railway bridge in Scotland, which was completed in 1890. His engineering expertise and visionary ideas played a crucial role in the bridge's design, making it an iconic symbol of engineering achievement and a UNESCO World Heritage Site.
