The Slater family is an American philanthropic, political, and manufacturing family from England, Rhode Island, Massachusetts, and Connecticut whose members include the "Father of the American Industrial Revolution," Samuel Slater, a prominent textile tycoon who founded America's first textile mill, Slater Mill (1790), and with his brother John Slater founded Slatersville, Rhode Island in North Smithfield, Rhode Island in 1803, America's first planned mill village.
 The family includes various merchants, inventors, art patrons, and socialites.
 John Fox Slater, was a prominent abolitionist who founded the Slater Fund and built the historic John F. Slater House and Slater Library.
 William A. Slater was a noted art collector and philanthropist who created the Slater Memorial Museum in Connecticut.
 After moving many of their mills to the South from New England, the village of Slater-Marietta, South Carolina was named after the family.
The Second Industrial Revolution, also known as the Technological Revolution, was a phase of rapid industrialization in the final third of the 19th century and the beginning of the 20th.
 The First Industrial Revolution, which ended in the early to mid 1800s, was punctuated by a slowdown in macroinventions before the Second Industrial Revolution in 1870.
 Though a number of its characteristic events can be traced to earlier innovations in manufacturing, such as the establishment of a machine tool industry, the development of methods for manufacturing interchangeable parts and the invention of the Bessemer Process to produce steel, the Second Industrial Revolution is generally dated between 1870 and 1914 up to the start of World War I.
The Hope Village Historic District encompasses a historic mill village located in Scituate, Rhode Island.
 Located on a bend in the Pawtuxet River in southeastern Scituate, the area has seen industrial activity since the 18th century, and has surviving industrial and residential buildings from the early 19th century.
 The village is centered on the junction of Main Street (Rhode Island Route 115) and North Road (Rhode Island Route 116), and radiates out from there, with numerous properties on smaller side streets.
 The present main mill building was built in 1844 by Brown & Ives, operators of numerous Rhode Island textile mills.
 Approximately 1/4 of the village's housing stock originated as mill worker housing built by the company.
Jerry Wheelock (1784–1861) was an early industrial pioneer in the Blackstone Valley of Massachusetts, a region that incubated the early American industrial revolution.
Blackstone River Valley National Historical Park is a National Park Service unit in the states of Rhode Island and Massachusetts.
 The park was created for the purpose of preserving, protecting, and interpreting the industrial heritage of the Blackstone River Valley and the urban, rural, and agricultural landscape of that region.
 The Blackstone River Valley was the site of some of the earliest successful textile mills in the United States, and these mills contributed significantly to the earliest American Industrial Revolution.
 The subsequent construction of the Blackstone Canal, a few years after the successful completion of the Erie Canal, helped to sustain the region's industrial strength.

John Slater (December 25, 1776–1843) was an early American industrialist, founder of Slatersville, Rhode Island and younger brother of Samuel Slater, father of the American Industrial Revolution, and a member of the well-known Slater family.
Stephen Northup (roughly 1630 – after 1687) was an early settler of the Colony of Rhode Island and Providence Plantations, and built what may be the oldest house still standing in Rhode Island.
 Northup was a fairly early settler of Providence in the Rhode Island colony, but accounts claiming that he settled the area with Roger Williams are inaccurate, since Northup was an infant or child when Williams first came to Providence in the spring of 1636.
 Northup lived in Providence from 1655 to 1666, after which he moved to the Narragansett country (what is now North Kingstown, Rhode Island), which land was claimed by both the Rhode Island and Connecticut colonies.
 He may have owned or operated a grist mill, and is credited with building a house that still stands and is used as a private residence.
 Northup was married, had six known children, and lived until at least 1687, when he was taxed.
 He was the great grandfather of Capt. Henry Northup who left Rhode Island to settle in Hoosick, New York, and took his slave Mintus who was manumitted in 1797.
 Mintus assumed the surname Northup, and had a free-born son, Solomon Northup, the subject of the Academy Award winning film 12 Years a Slave.
Samuel Slater (June 9, 1768 – April 21, 1835) was an early English-American industrialist known as the "Father of the American Industrial Revolution" (a phrase coined by Andrew Jackson) and the "Father of the American Factory System."
 In the UK, he was called "Slater the Traitor" because he brought British textile technology to America, modifying it for United States use.
 He learned textile machinery as an apprentice to a pioneer in the British industry, then immigrating to the United States at the age of 21.
 He designed the first textile mills in the US and later went into business for himself, developing a family business with his sons.
 A wealthy man, he eventually owned thirteen spinning mills and had developed tenant farms and company towns around his textile mills, such as Slatersville, Rhode Island.
