Harry F. Miller signed Edison Portland Cement Co Stock Certificate - Transferred to Thomas A. Edison Inc. at BackInv# AG1286 Stock
In 1881 Edison formed the Edison Ore-Milling Company and tried for many years to make that business a success. The demand was not existent, though new technological innovations that Edison brought to the industry the company could not compete with operations in the Midwest. Despite continual investment, with Edison selling shares in General Electric, the company suffered huge losses. Eventually, the ore-crushing technology was sold to other mine owners.
The manufacturing process used by the Edison Ore-Milling Company produced a large quantity of waste sand which he would sell to cement manufacturers. The properties of the fine sand were particularly suitable for concrete, leading to a harder, more durable product. In 1899, Edison decided to join the cement business, reusing some of the technology he had developed for ore-milling. The company only lasted a few years after the construction of the Yankee Stadium, falling victim to the Great Depression. Read more at https://en.wikipedia.org/wiki/Edison_Portland_Cement_Company
A stock certificate is issued by businesses, usually companies. A stock is part of the permanent finance of a business. Normally, they are never repaid, and the investor can recover his/her money only by selling to another investor. Most stocks, or also called shares, earn dividends, at the business's discretion, depending on how well it has traded. A stockholder or shareholder is a part-owner of the business that issued the stock certificates.
