Cream cheese is a soft, usually mild-tasting
fresh cheese made from milk and
cream
Cream is a dairy product composed of the higher-fat layer skimmed from the top of milk before homogenization. In un-homogenized milk, the fat, which is less dense, eventually rises to the top. In the industrial production of cream, this proces ...

Brie and
Neufchâtel. It is more comparable in taste, texture, and production methods to

defines cream cheese as containing at least 33%
milk fat with a moisture content of not more than 55%, and a
pH range of 4.4 to 4.9. Similarly, under Canadian Food and Drug Regulations, cream cheese must contain at least 30% milk fat and a maximum of 55% moisture.
In other countries, it is defined differently and may need a considerably higher fat content.
Cream cheese originated in the United States in the 1870s.
Origin
Around 1873, William A. Lawrence, a dairyman in
Chester, New York, was the first to mass produce an unripened fresh cheese known generically as cream cheese. In 1872, he began manufacturing
Neufchâtel cheese. By adding cream to the process, he developed a richer cheese that he called "cream cheese".
In 1877, Lawrence created the first brand of cream cheese; its logo was a silhouette of a cow followed by the words "Neufchatel & Cream Cheese".
In 1879, to build a larger factory, Lawrence entered into an arrangement with Samuel S. Durland, another Chester merchant.
In 1880, Alvah Reynolds, a New York cheese distributor, began to sell the cheese of Lawrence & Durland and called it "
Philadelphia Cream Cheese".

Philadelphia

, Pennsylvania, or
Philadelphia, New York, are incorrect.
By the end of 1880, faced with increasing demand for his Philadelphia-brand cheese, Reynolds turned to Charles Green, a second Chester dairyman, who by 1880 had been manufacturing cream cheese as well. Some of Green's cheese was also sold under the Philadelphia label.
In 1892, Reynolds bought the Empire Cheese Co. of
South Edmeston, New York, to produce cheese under his "Philadelphia" label. When the Empire factory burned down in 1900, he asked the newly formed Phenix Cheese Company to produce his cheese, instead. In 1903, Reynolds sold rights to the "Philadelphia" brand name to the Phenix Cheese Company, which was under the direction of Jason F. Whitney, Sr. (which later merged with
Kraft, in 1928).
By the early 1880s, Star cream cheese had emerged as Lawrence & Durland's brand, and Green made World and Globe brands of the cheese. At the turn of the 20th century, New York dairymen were producing cream cheese sold under such other brands as Triple Cream (C. Percival), Eagle (F.X. Baumert), Empire (Phenix Cheese Co.), Mohican (International Cheese Co.), Monroe Cheese Co. (Gross & Hoffman), and Nabob (F.H. Legget).
[''W.A. Lawrence et al v. P. E. Sharpless Co.'' (1912)]
Cream cheese is common in the
Ashkenazi Jewish cuisine of New York City, where it is known as a "
schmear". It is the basis of the
bagel and cream cheese, an
open-faced sandwich.
