Henry George Clopper Ketchum

Education and career Ketchum attended grammar school at the Fredericton Collegiate School. In 1854, he enrolled in a lecture series given by English engineer Thomas McMahon Cregan at King's College in Fredericton. That same year, the college released engineering students to gain practical experience working in railway construction during the summer.

From 1856 to 1860, Ketchum worked on the European and North American Railway. He first worked as a surveyor on construction of the line from Halifax, Nova Scotia to Bangor, Maine, under Edward Barron Chandler. Later, he was promoted to assistant construction engineer under chief engineer Alexander Luders Light, working on the E&NA "Eastern Extension" line from Saint John to Shediac. Under Ketchum's supervision the project was completed in seven months.

After completion of his São Paulo projects, Ketchum travelled to London, where he was granted a prize of "in testimony to his ability as an engineer and his integrity and zeal as agent." Ketchum's plans and blueprints for the project were destroyed in the 1877 Great Fire of Saint John.

Legacy Ketchum's will provided for a silver medal to be created as an academic prize at the University of New Brunswick. The Ketchum Memorial Medal was designed by the Allan Wyon Company of London, England, in the spring of 1897, and was first awarded that year. It is awarded annually to the graduating full-time civil engineering student with the highest standing.

The stone arch bridge constructed near Tidnish Cross Roads for the Chignecto Marine Transport Railway was listed on the Canadian Register of Historic Places in 1985, and stands to this day. The railway's lands were purchased by the government of Nova Scotia in 2012, and converted to a hiking trail. A suspension bridge was constructed for the trail to cross the Tidnish River, and was named the Henry G. C. Ketchum Memorial Suspension Bridge.
