Martin P. Eidelberg (born January 30, 1941) is an American professor emeritus of art history at Rutgers University and an expert on ceramics and Tiffany glass.
 He is noted for discovering that many floral Tiffany lamp designs were not personally made by Louis Comfort Tiffany, but by an underpaid and unrecognized woman designer named Clara Driscoll.
Tiffany jewelry was the jewelry created and supervised by Louis Comfort Tiffany at Tiffany & Co., during the Art Nouveau movement.
Laurelton Hall was the home of noted artist Louis Comfort Tiffany, located in Laurel Hollow, Long Island, New York.
 The 65-room mansion on 600 acres of land, designed in the Art Nouveau mode, combined Islamic motifs with connection to nature, was completed in 1905, and housed many of Tiffany's most notable works, as well as serving as a work of art in and of itself.
Education is a stained-glass window commissioned from Louis Comfort Tiffany's Tiffany Glass Company during the building of Yale University's Chittenden Hall (now Linsly-Chittenden Hall, after being connected to a nearby building), funded by Simeon Baldwin Chittenden.
 Personifications of Art, Science, Religion, and Music are represented in the work, as angels.
 Other angelic representations of related virtues, values, and ideas attend them, each identified by words in their halos.
S. Alfred Hopkins (1870 — May 1941) was an American architect, an "estate architect" who specialized in country houses and especially in model farms in an invented "vernacular" style suited to the American elite.
 His practice, established in 1912 as Alfred Hopkins & Associates, was mostly based in New York, where he was the "dean of farm group architecture," in Westchester County, northern New Jersey and Long Island; he also built two gentlemen's farms in Illinois.
 He built fifteen of his practical and esthetic farm group complexes on Long Island, including one for Louis Comfort Tiffany at Laurelton Hall.
 An article on farm groupings published in "Architectural Record" in 1915 notes that Hopkins was often called upon to design the farm groups on estates where the residences were the work of other architects, such as Bertram Goodhue, John Russell Pope and Charles A. Platt.
Brown Memorial Park Avenue Presbyterian Church of Baltimore, Maryland, U.S., is a large, Gothic Revival-style church built in 1870 and located at Park and Lafayette Avenues in the city's Bolton Hill section.
 Named in memory of a 19th-century Baltimore financier, the ornate church is noted for its exquisite stained glass windows by renowned artist Louis Comfort Tiffany, soaring vaulted ceiling, and the prominent persons associated with its history.
 Maltbie Babcock, who was the church's pastor 1887–1900, wrote the familiar hymn, "This is My Father's World".
 Storied virtuoso concert performer Virgil Fox was organist at Brown Memorial early in his career (1936–1946).
The Louis Comfort Tiffany Foundation was founded in 1918 by Louis Comfort Tiffany to operate his estate, Laurelton Hall, in Cold Spring Harbor, Long Island.
 It was designed to be a summer retreat for artists and craftspeople.
 In 1946 the estate closed and the foundation changed its purpose from a retreat to the bestowing of grants to artists.
The Haworth Art Gallery is a public art gallery located in Accrington, Lancashire, northwest England, and is the home of the largest collection in Europe of Tiffany glass from the studio of Louis Comfort Tiffany.
 The museum, a Tudor-style house, was originally built in 1909 to be the home of William Haworth, a manufacturer of textiles.
 The house was designed by Walter Brierley (1862–1926, a York architect known as "the Yorkshire Lutyens".
 It was bequeathed to the people of Accrington in 1920, and stands in nine acres of parkland on the south side of Accrington Town Centre.

 He was affiliated with a prestigious collaborative of designers known as the Associated Artists, which included Lockwood de Forest, Candace Wheeler, and Samuel Colman.
 Tiffany designed stained glass windows and lamps, glass mosaics, blown glass, ceramics, jewelry, enamels, and metalwork.
 He was the first Design Director at his family company, Tiffany & Co., founded by his father Charles Lewis Tiffany.
Elmwood, also known as "The Cliffs," is a historic home located at Oyster Bay in Nassau County, New York.

 The original house is a 2-story, gable-roofed, five-by-three-bay wood-frame house.
 It was expanded about 1915 during its ownership by Charles L. Tiffany II (1878–1947), nephew of Louis Comfort Tiffany (1848–1933).
 It features a prominent cornice and architrave and an imposing tetrastyle Ionic order portico.
 Also on the property are an assortment of 19th century dependencies including a gazebo, tool shed, ice house, greenhouse, barns, and a brick coach house built in 1918 by Mr. Tiffany.
