New York Hospital under construction, 1940. The original New York Hospital was founded in 1771 by Edinburgh graduate Samuel Bard in lower Manhattan. The hospital moved a number of times in the ensuing centuries until it landed at its current location in 1932 (it had become affiliated with Cornell University a few years earlier in 1927).

Mount Vernon Hotel Museum ARCHITECT: Unknown DATE: 1799 STYLE: Federal The charm of this Federal style stone stable converted into a comfortable headquarters for the Colonial Dames is to be found in its superb masonry construction and its excellent proportions. The sharp profiles of the low pitched pedimented gable roofs cut a clean line that is both severe and pleasing to the eye. A smooth-faced stone belt-course separates the rock-faced masonry of the lower floor from that of the second story clearly defining the building’s perimeter.

Col. Smith House (also known as the Adams Mansion), 1924. This building was originally a carriage house on the estate of Colonel William S. Smith, aide-de-camp to Washington and husband of Abigail Adams, the daughter of President John Adams. The estate was known as "Smith's Folly." After his failure in business, about 1800, the buildings were brought by William T. Robinson and were said to have been completed by him. In 1826 the main house burned, and in 1830 the carriage house was bought by Jeremiah Towle, remaining in the possession of his family until 1906. It was later purchased by the Colonial Dames of America.

Schermerhorn Farmhouse ca. 1913 The Schermerhorn Farmhouse, built in 1747, was located on a peak overlooking the East River on the southern edge of the Schermerhorn Farm, which spanned from the East River to Third Avenue between 63rd and 68th Streets. The farmhouse was likely built by the Hardenbrook family, who owned the southern portion of the farm before it was purchased by Peter Schermerhorn. Tradition holds that the farm was once the country home of Governor George Clinton, who served as a member of Continental Congress, Governor of New York State, and Vice President of the United States for two terms under Thomas Jefferson and James Madison. The Schermerhorn estate was purchased by John D. Rockefeller in 1903 as the site for the Rockefeller Institute of Medical Research. The farmhouse was demolished in 1914 and the site is now home to the Rockefeller University campus.

We know there's a lot of stressful news in your timeline, so here's a round-up of calming images for a #MuseumMomentofZen.

Riverview Terrace at the foot of Sutton Square, ca. 1977. This iconic view of the East River and the Queensboro Bridge was made famous by Woody Allen's 1979 film, "Manhattan." Riverview Terrace itself (out of frame at left) is a private cobblestoned block, once part of an 1878 development of 24 townhouses, of which six remain.

Allan Stillman, the founder of "T.G.I. Fridays" unknowingly created what would become one of the most beloved and hated eating establishments of its era. Stillman, a perfume salesman, put down $5,000 (plus an additional $5,000 he borrowed from his mom) to turn a divey boy's bar into a hoppin' singles hangout, velvet ropes and all. Read on to learn the history of T.G.I. Fridays.

New York Hospital-Cornell Medical Center (now NewYork-Presbyterian/Weill Cornell Medical Center), ca. 1931. The view is from Roosevelt Island, then known as Welfare Island.

Mount Vernon Hotel Museum and Garden, ca. 1939. Located on 61st Street between 1st and York Avenue, this plot was originally purchased by Colonel William S. Smith, a Revolutionary War veteran and politician. Smith found the property with his wife, Abigail Adams, the daughter of founding father and second U.S. President John Adams. The two bought the land with intentions to develop it into an estate called "Mount Vernon," named for George Washington's plantation in Virginia. The couple eventually sold the land, never beginning construction of their planned estate. Instead, William T. Robinson, who owned a house nearby, purchased the property to build a stone carriage house and stable. He continued to call the area "Mount Vernon." Unfortunately, Robinson's main estate was lost to a fire in the 1820s. In 1826, the former carriage house was converted into a hotel by Joseph Coleman Hart. Surrounded by rural lands, the stone house provided an easy getaway for Manhattanites looking to spend a day in the country. In an era with no public parks, the area provided New York City's elite with a place to roam free and participate in many activities, such as boating and hiking in proximity to the East River. Mount Vernon was more of a country club than a hotel, and many guests returned home to the city in the evenings by steamboat or stagecoach. The hotel closed in 1833, likely put out of business by nearby competitors. It was purchased by Jerimiah Towle and converted into a private residence for his family. As photographs indicate, by the early 20th century the Standard Light and Gas Company began building tanks in the vicinity of the property and eventually purchased the home in 1905. The building's ownership was eventually passed down to the Colonial Dames of America, a patriotic society, who converted the former hotel into their headquarters in 1924. Coinciding with the New York's World's Fair, the building was converted into the Abigail Adam Smith Museum, which was later renamed the Mount Vernon Hotel Museum and Garden to better reflect its history. The Colonial Dames of America still operate the Hotel Museum and Garden, which focuses on the history of New York City after the construction of the Erie Dam in 1925.

The Memorial Hospital (now part of Memorial Sloan Kettering) moved to its new location following a donation of land and millions of dollars from John D. Rockefeller Jr. amongst others. Officially reopening in 1939, the Memorial Hospital was one of the city's leading cancer hospitals.

Col. Smith House (also known as the Adams Mansion), 1924. This Federal style structure was originally built as the carriage house for the large 23-acres estate of John Adams' daughter Abigail and her husband, William Stephens Smith. Despite grand plans and an idea to name the estate after George Washington's home, the Smiths were forced to sell the estate due to financial troubles. This building was completed in 1799 by the next owner, William T. Robinson, a well-to-do merchant. By the 1820s the building and its nearby structures and land were purchased and converted in the Mount Vernon Hotel, which was a day hotel catering to a rising middle class looking to escape the crowding and congestion of downtown. The hotel would only stay open for seven years. For the rest of the 19th and early 20th century it was a private residence. The building was sold to Standard Gas and Light Company in 1905. The Colonial Dames of New York purchased it in 1924 (the year this photo was taken) and turned it into a museum. It has continued in that capacity into the 21st century.

Abigail Adams Smith House, 1935.

Public School 183, 1920. A C.B.J. Snyder school was constructed in 1902 and opened in 1903. The school has a long history of promoting science-based learning and has been nicknamed the "School of Discovery." Today the school remains P.S. 183 and is named after Robert Louis Stevenson, the Scottish novelist and travel writer.

Rockefeller University (formerly Institute), ca. 1980.

Originally founded in 1895 by Slovakian immigrants on the Lower East Side, the Church of St. John Nepomucene moved north to East 57th Street, before finally settling in Yorkville at First Avenue and 66th Street. Their current building, seen here in 1927 two years after it was completed, was designed in a Romanesque Revival Style by architect John van Pelt. The prominent tower, rose window, and brick and stone facade with intricate details stand out along the busy avenue to this day.

67th Street Branch, NYPL, July 26, 1930. Built in 1905 by Babb, Cook & Willard, the 67th Street Library has the Italian Renaissance Revival design of many of the Manhattan Carnegies. The most distinctive feature of the building is the unusual Art Nouveau transom window above doorway (seen at right).
