H. Gildersleeve

Overview:

Henry Gildersleeve (1791–1851) was a prominent shipbuilder based in Ernestown, Ontario (now Loyalist Township). He played a pivotal role in constructing some of the most significant vessels of his time, including the Frontenac, Canada’s first steamship to operate on the Great Lakes. Gildersleeve’s contributions to early Canadian maritime history highlight his skills as a master craftsman and his influence on the region’s shipbuilding industry during the early 19th century.

Role in the Construction of the Frontenac:

• Completion of the Frontenac:

• While the vessel was initially started by Teabout & Chapman, it was H. Gildersleeve who completed the Frontenac in 1816 at his shipyard in Ernestown.

• His expertise ensured the successful launch of this groundbreaking steamship, which marked a turning point in transportation technology on the Great Lakes.

• Innovative Approach:

• The Frontenac was equipped with a Boulton & Watt steam engine—a significant engineering marvel for its time, imported from London. Gildersleeve’s ability to incorporate such advanced technology demonstrates his adaptability and innovative mindset.

Background and Career:

• Shipbuilding in Ernestown:

• Ernestown, located on the northern shore of Lake Ontario near Kingston, was a key site for shipbuilding in the early 19th century due to its proximity to the Great Lakes’ major trade routes. Gildersleeve’s shipyard was among the most active and renowned in the area.
