John Elder

Died 17 Sep 1869 at age 45 (born 8 Mar 1824).Scottish marine engineer who, assisted by W.J.M. Rankine, developed the compound steam marine engine (1854) by dividing the steam expansion into two cylinders, so that each cycled through a smaller range of temperatures and pressures which greatly improved fuel efficiency. The S.S. Brandon sailed in Jul 1854 with their first engine of this type, which used a third less coal than was possible before. Elder continued improve his designs to give even more economy. As a result, his engineering business on the Clyde in Glasgow, Scotland, continued to grow, with over 4,000 workers. Between 1853 and 1867, his firm took out fourteen important patents, including a quadruple-expansion engine (1862). He died at the young age of 45 from liver disease. However, his ship yard remains today as Kvaerner Govan Ltd.«
