Question: When was the company incorporated that produced Heroes United?

Knapp, Stout & Co. was a lumber company based in Menomonie, Wisconsin in the 19th and early 20th centuries.  The company was established in 1846, when John Holly Knapp and William Wilson purchased half of interest in a lumber mill on the Red Cedar River from David Black; it was originally known as Black & Knapp.  Later Andrew Tainter acquired a quarter-interest, and the company has become Knapp-Tainter Lumber Company.  Henry Stout bought a quarter interest in the company in 1853, and its name became Knapp, Stout & Company.  The company's location allowed it to control the lumber industry in the region, and by 1870 it controlled the logging industry in the Red Cedar River valley.  In 1878, the company incorporated, and its official name became the Knapp, Stout & Co., Company.  The company employed over 2,000 workers in the Menomonie area and produced 85 million board feet of lumber on average yearly from 1871 to 1896; its output made it the largest lumber company in the world.  In the 1880s, the company expanded to sites along the Mississippi River, opening offices in Dubuque, Iowa, Read's Landing, Minnesota, and St. Louis.  By the 1900s, the company had largely depleted its lumber supply; it closed many of its camps and dissolved early in the 20th century.  The company sent out its last shipment of lumber on August 12, 1901. <SEP> Heroes United is a series of direct to video films from Marvel Animation and the first from its own studio outside any joint ventures. <SEP> Morse Diving is an American manufacturer of diving equipment.  It was founded in 1837 as Morse & Fletcher in Boston MA.  The name was changed in 1864 to A J Morse and Son and it remained under that name until 1905 when the company was incorporated and Inc. was added to the name.  In 1940 the company was purchased and the name was changed to Morse Diving Equipment Company Incorporated and later moved its operations to Rockland, MA and continued under that name until 1998 when it was purchased by Kenneth Downey, an employee, and did business under the name of Morse Diving Inc.  Downey sold the company in 2014 to Watson "Robbie" Holland, and the name changed, yet again, to Morse International.  Morse filed for bankruptcy and Diving Equipment and Supply Company (DESCO) acquired its assets in 2016.  DESCO reverted to the name A J Morse & Son and Morse products will be marketed under that name.  DESCO's business plan is to bring back the quality and products associated with the earlier name.  DESCO has on re-introduced the breast plate feed (air being fed into the breast plate rather than the bonnet)helmet design from the early 1900s as its first offering.  They also make the standard commercial model with the air feed in the rear of the helmet.
