The Pennsylvania School for the Deaf is the third-oldest school of its kind in the United States. Its founder, David G. Seixas (1788–1864), was a Philadelphia crockery maker-dealer who became concerned with the plight of impoverished deaf children who he observed on the city's streets. The current school building is listed by the National Register of Historic Places, and two former campuses are similarly recognized. It is one of four approved chartered schools—along with the Western Pennsylvania School for Blind Children, the Overbrook School for the Blind, the Western Pennsylvania School for the Deaf—in Pennsylvania.

Brown Instrument Company was a U.S. firm known for high-quality instruments (such as pyrometers, thermometers, hygrometers, tachometers, pressure gauges, flow meters, ammeters, and voltmeters) and industrial controls. The company was founded in 1857 in Philadelphia by Edward Brown, inventor of the first pyrometer of American design. In 1934, the firm became a division of Honeywell. The company was a large employer in North Philadelphia during most of the 20th century. A large brick factory building across Windrim Avenue from Wayne Junction, currently Extra Space Storage, was a principal Brown Instrument Company building. A 1921 catalog mentions laboratories here. The Wayne Avenue façade still has "Brown Instrument Co" relieved into the concrete. A Google Book search for "Brown Instrument" "Wayne Ave" shows multiple addresses for the company on the 4400 and 4500 blocks of Wayne Ave, which straddle Wayne Junction. Another search result from 1915 mentions 311 Walnut St. Across the regional rail tracks from Fern Rock Transportation Center there is another old factory building topped by a sign marked "Honeywell – Brown Instrument Division". The firm later moved to Fort Washington, Pennsylvania. Honeywell's automation and control businesses still have a campus there, although the Brown Instrument name has been retired.

Nicetown–Tioga is a neighborhood in the North Philadelphia section of the city of Philadelphia, in the U.S. state of Pennsylvania.

The Keystone Dry Plate and Film Works was founded by John Carbutt in 1879 in Philadelphia, and its 113 Berkley Street location was constructed in Germantown in 1884. The factory became the location for his pioneering work in new photographic technologies, including improved glass plate photography, x-ray imaging, the first 35 mm celluloid film, and very early color photography procedures. Carbutt developed the first gelatine-bromide dry plates (1879), the first orthochromatic dry plates (1886) and the first celluloid dry plates(1888) in this location. He produced the first 35mm film here and sold it to Thomas Edison. In 1888, he introduced the less than a decade-old Edison light bulb to increase productivity in his factory, and in 1896, Carbutt began to manufacture the first x-ray plates for commercial use. In his later years, Carbutt experimented with color photography.John Carbutt died in 1905. In the early 20th century the factory was bought by Defender Photo Supply, based in Rochester, NY, and became known as the Defender Dry Plate Company. From 1912 to 1977 the building was occupied by Moore Push Pin Company; Edwin Moore invented and patented the push pin, and subsequent occupants included a drug rehab facility. The building forms part of a cluster of 19th-century industrial buildings around Wayne Junction rail station. In January 2021, Ken Weinstein, the current owner of the property through Wayne Junction Properties/Philly Office Retail, submitted a financial hardship application to the Philadelphia Historical Commission to permit the building to be demolished.

Bellevue Mansion was a historic country house in North Philadelphia. The site on which it stood is now between North Marston and North Etting Streets, near 29th Street and Allegheny Avenue. Bellevue was purchased from Thomas Ketland and his wife Elizabeth as a country estate in 1802 by Philadelphia merchant Charles Wharton (1743–1838), grandfather of industrialist Joseph Wharton. It was located about 3 miles (4.8 km) northwest of Philadelphia, just below the heights of Germantown. Bellevue remained in the Wharton family for more than 60 years. In 1834 Charles Wharton gave the estate to his son William (1790–1856), who resided there in the summer with his wife Deborah Fisher Wharton for two decades raising their family. It was a working farm of 106 acres (0.43 km2), situated in rolling hills, with house, barn, sheds, vegetable gardens, orchards, fields, and farm animals. The manor house overlooked a small valley and brook that flowed into the Schuylkill River. Large willows, sycamores, and oaks dominated the house and landscape. Servants, mostly Irish, assisted with housekeeping and hired hands worked the fields and maintained the farm animals. The estate was surrounded by woods and estates of other wealthy Philadelphians. Bellevue Mansion was large and roomy, constructed in stone, with two stories, basement, and widow's walk on the roof. Originally constructed by an Englishman who enjoyed dancing, it contained a large ballroom, used by the Wharton family as a game room. The family visited Bellevue often, entertaining many guests young and old. Paralleling the creek nearby was Nicetown Lane, leading about a half mile down to the Schuylkill River. William and Deborah were heavily involved in religious affairs of their Quaker Meeting and in the period 1825 to 1840 depended on Bellevue with its housemistress to keep their children occupied during the summer months. Joseph Wharton and his brother Charles and their siblings often walked down Nicetown Lane to the Schuylkill River, where they cooled off during the summer. Starting in the 1840s, Bellevue was threatened by local development. In 1839, the Reading Railroad built its main line from Philadelphia to Norristown and north to Reading. The line ran about 30 yards (27 m) from the mansion on the north. The surrounding land, between Germantown and the city limits of Philadelphia, today's North Philadelphia, was relatively undeveloped, and in the period 1850 to 1880 entrepreneurs bought up many of the old estates for industrial sites and housing developments. To the younger generation of that time, the railroads represented progress, allowing anyone to travel quickly and boosting the economy of the region. This was especially true for Joseph Wharton and his siblings, who accepted such worldly improvements, and became immersed in the industrial economy. The trains were convenient, with a "Bellevue" station within a short walk of the mansion. But they also carried huge loads of coal, thundering by the house at inconvenient times, and the constant noise was annoying for guests staying at Bellevue. Although still a beautiful estate, its utility as a respite from city life would be limited. In 1854, Philadelphia expanded its borders to include the surrounding suburbs, and after the Civil War its population swelled to several hundred thousand. By 1870 the Centennial Exposition was upcoming, and Philadelphia was rapidly changing. It was suffering from a water crisis because it required more water, but there was no appropriate method for water purification and the Delaware and Schuylkill rivers were heavily polluted. Philadelphia's typhoid fever rate was among the highest in the nation, and most well-to-do families drank bottled spring water. Although Bellevue had been threatened since the 1840s by the proximity of the nearby railroads, it was now threatened more directly. In the 1870s the entire Bellevue estate, then owned by Joseph Wharton and his siblings, along with several other estates nearby that had been annexed into the city, was threatened with condemnation by the city for the construction of the proposed Cambria Reservoir to hold potable water. The Wharton siblings were angry and frustrated that there seemed no recourse when the city chose their estate on which to build. Joseph Wharton saw a potential solution to the water problems. He started purchasing land in southern New Jersey in the 1870s, eventually acquiring 150 square miles (390 km2) in the Pinelands, which contained an aquifer replenished by several rivers and lakes. The water from the Pinelands was relatively pure and he planned to export the water to Philadelphia. Wharton suggested that a city-controlled company could develop the necessary water mains and pumps, funded by public purchase of stocks and bonds. There was opposition to the plan by others in Philadelphia and in New Jersey, and eventually a law was passed in New Jersey preventing the export of water. The Bellevue estate was taken by the city, but the planned reservoir was never constructed, because of local politics and also because by 1890 water could be purified by filtration, obviating the need for an extra reservoir. Instead most of the Bellevue estate was sold to developers. Unmaintained and boarded up, the mansion was used for several decades by the city water department to store pipes and fittings, and was finally demolished in construction of new housing for the newly organized industry nearby in North Philadelphia. Today, the location of Bellevue Mansion is Etting Square, a small park and playground between N. Marston and N. Etting Streets, just north of Allegheny Avenue in North Philadelphia.
