Samuel Honeyman Kneass (1806–1858) was an American civil engineer and architect.
[1] In 1837 and 1838, Kneass was the lead engineer during the Philadelphia, Wilmington and Baltimore Railroad's construction of the Newkirk Viaduct, the Schuylkill River bridge that completed the first rail link between the cities.
On March 14, 1837, Kneass married Anna Lombaert (1814-1869) in Morrisville, Pennsylvania.
His 1853 report to the city was "the first attempt to systematize the disparate sewers and sewerage systems in place in various municipalities around the time of Philadelphia's consolidation.
"[3][4] He was succeeded in the job by his younger brother, Strickland, who served as Chief Engineer & Surveyor from the city's consolidation in 1855 until his retirement in 1872.
