Isambard Kingdom Brunel was a legendary 19th century British engineer who made significant contributions to infrastructure and transportation projects. Some of his most notable achievements included designing the Thames Tunnel, Clifton Suspension Bridge, Great Western Railway, and three revolutionary steamships. As a project manager, Brunel demonstrated strong leadership and vision in promoting ambitious projects. However, he sometimes struggled with delivering projects on time and budget, and a few projects like the Atmospheric Railway and Thames Tunnel were not financially viable. Overall, Brunel showed great engineering skill and innovation, but his intense focus on perfection and disregard for costs and schedules meant that not all his projects were successful from a project management perspective.
