Schlesinger, Davis & Co, Wallsend. Builders of the Londoner. Charles Albert Schlesinger was a former apprentice at Robert Stephenson's works at Newcastle and Frederick Blake Davis had trained at Charles Mitchell's yard at Low Walker. Davis had also worked for Mitchell in India for four years before he partnered with Schlesinger.They opened a yard together in Wallsend in 1863. Two sailing ships were launched before their first steamer LLANDAFF was launched in 1865. The yard remained in operation for over 30 years and produced a total of 167 vessels including, in 1868, the KIELDER CASTLE, the first Schlesinger Davies vessel of over 1000 tons. In 1880 Davis bought out Schlesinger due to Schlesinger's increasing health issues. However, in the early 1890s the company started to fail as ship construction declined across the whole country and the yard finally closed in 1893. In 1897 the yard was bought by CS Swan & Hunter for the construction of floating dry docks. (Courtesy of Tyne Built Ships)
