Under the new partnership of Leavenworth, Hayden & Scovill of 1811, the company continued to produce brass buttons, including a military contract to produce civil war artillery buttons.

Having been already set up for the production of metal items, J.M.L Scovill and W.H. Scovill began manufacturing silvered plates in 1839, shortly after the presentation of Daguerreotype photography. In about a year, Scovill plates were of equal quality to plates manufactured in Paris.

The Scovills became notable suppliers of photographic supplies after opening a New York storefront in 1846, which carried a full line of cameras, photographic equipment and supplies.

The Scovill company continued to grow; it was incorporated as Scovill Manufacturing Company in 1850 and acquired the American Optical Company in 1867. This broadened their manufacturing line to include the box cameras and stereoscopes produced by American Optical.

Some organizational change followed when, in 1889, an officer took over the company, changing the name to Scovill & Adam's. The company's name changed again, to The Scovill & Anthony Company, when it merged with the E. & H.T. Anthony Company in 1902.

In 1907, this handle was abbreviated to "ANSCO". The company continued to produce photographic equipment under that brand name until 1928, when they merged with the German manufacturer, Agfa.

The Assembly of First Nations (AFN) is a national advocacy organization representing First Nation citizens in Canada, which includes more than 900,000 people living in 634 First Nation communities and in cities and towns across the country.
In 1982, the Assembly of First Nations (AFN) was created as a result of movements to restore chiefs as the voice of First Nations in a Canada-wide deliberative assembly. Prior to that time, the Canada-wide representation of Indigenous peoples in Canada occurred through the National Indian Brotherhood (NIB), which centred on representation through provincial organizations (several of these organizations began as early as the 1920s, and many were based on political traditions dating from before European contact). The NIB had succeeded the National Indian Council (founded 1961) and represented Aboriginal interests throughout the 1960s and 1970s under leaders Walter Dieter, George Manuel and Noel Starblanket. In the late 1970s, First Nations increasingly pushed for the rights of self-government. In 1979, hundreds of First Nations met in London, England, and determined to establish a new organization, and to stop patriation. Hundreds of chiefs met in Ottawa the following year, outlining their relationships with Canada and with one another in a manifesto entitled the Declaration of First Nations (signed in December, 1980). At the National Indian Brotherhood general assembly in 1982, the Assembly of First Nations was officially founded.
