Hand squirts and hand pumps are noted before Ctesibius of Alexandria invented the first fire pump around the 2nd century B.C., and an example of a force-pump possibly used for a fire-engine is mentioned by Heron of Alexandria. A book of 1655 inventions mentions a steam engine (called a "fire engine") pump used to "raise a column of water ", but there was no mention of whether it was portable. Colonial laws in America required each house to have a bucket of water on the front stoop in preparation for fires at night. These buckets were intended for use by the initial bucket brigade that would supply the water at fires. Philadelphia obtained a hand-pumped fire engine in 1719, years after Boston's 1654 model appeared there, made by Joseph Jenckes Sr., but before New York's two engines arrived from London. By 1730, Richard Newsham, in London, had made successful fire engines; he invented the first ones used in New York City (in 1731) (this was six years before formation of the NYC volunteer fire department). The amount of manpower and skill necessary for firefighting prompted Benjamin Franklin to found an organized fire company in 1737. Thomas Lote built the first fire engine made in America in 1743. These earliest engines are called "hand tubs" because they are manually (hand) powered and the water was supplied by a bucket brigade dumping it into a tub (cistern) where the pump had a permanent intake pipe. An important advancement around 1822 was the invention of an engine which could draft water from a water source. This rendered the bucket brigade obsolete. In 1822, a Philadelphia-based manufacturing company called "Sellers and Pennock" made a model called "The Hydraulion". It is said to be the first suction engine. Some models had the hard, suction hose fixed to the intake and curled up over the apparatus known as a squirrel tail engine. The earliest engines were small and were either carried by four men, or mounted on skids and dragged to a fire. As the engines grew larger they became horse-drawn and later self-propelled by steam engines. John Ericsson is credited with building the first American steam-powered fire engine. John Braithwaite built the first steam fire-engine in Britain. Until the mid-19th century, most fire engines were maneuvered by men, but the introduction of horse-drawn fire engines considerably improved the response time to incidents.
