The son of noted engineer Sir Marc Isambard Brunel, Isambard K. Brunel was born in Portsmouth, England on April 9, 1806. His father was working there on the block-making machinery of the Portsmouth Block Mills. The young Brunel was sent to France to be educated at the College of Caen in Normandy and the Lycée Henri-Quatre in Paris. He rose to prominence when, aged 20, he was appointed as the resident engineer of the Thames Tunnel, his father's greatest achievement. The first major river tunnel ever built, Isambard spent nearly two years trying to drive the horizontal shaft from one side to the other. Two severe incidents of flooding injured the younger Brunel and ended work on the tunnel for several years, though it was eventually completed.
