A Sampling of African-American Inventors and Their Inventions

Emmit McHenry and his partners were ahead in the technology game, but Blacks Business people refuse to join him.
In 1979, Emmit McHenry and a few associates start an engineering company name Network Solutions. For 16 years, he and his partners toiled away and built a solid company. They could not get money from the financial institute so they mortgage their properties and max out their credit cards. They were good engineers and got many contracts but the gem within Network Solutions was a contract with the National Science Foundation, which was to create the U.S. Government’s and World first domain name addressing system for the Internet. This was back when the Internet was just a government project, and its commercial potential hadn’t been realized.
Emmit McHenry created a complex computer code whereby ordinary people can now surf the web or have e-mails without having to study computer science. He created what we know today simply as .com
On Dec. 31 1992, Network Solutions got the contract that would make the company a legacy. After the government review several company proposals, The National Science Foundation Department selected Network Solution as manager of domain names registration service for the Internet.
The contract was for $1 million a year for five years. Network Solution had the sole authority to develop and issue Internet system for Web addresses. What Network Solution developed was .com, .net, .edu, and. gov. to communicate on the Internet.
At the time Network Solutions already was handling other sensitive engineering projects for the government. To keep up with the demands the company needed to hire more workers and buy new equipment, but the fixed $1 million a year contract proved to be a constrained because no matter how many names the company registered, it could not charge more. Over the years demand for domain names increase and the company staff grew to 400 employees. Emmit applied to the government to charge directly for the domain names as the request for names continued to increase by the thousands. The government refuses and continues to pay the company $1 million a year for as many requested domain names.
Emmit went to wealthy high profile Blacks and they all refuse to invest in his company. He tried the financial institute and Wall Street and they also said no. He got some help from a white fellow engineer but it was not enough. In the mean time the government keeps insisting if he could not keep up with the volume they will break the contract.
In 1995 Emmit sold Network Solutions to Science Applications International Corp or SAIC for 4.8 million plus personal and business debt. In a few months the government gives SAIC the rights to charge $70.00 per year for each domain name plus royalty on any other created domain names, the same request Emmit wanted. With millions of people and companies requesting domain names there was a bidding war to buy this new cash cow SAIC acquired. A Wall Street Company name VeriSign Inc. was the winner. SAIC flip the newly purchase 4.8 million company to VeriSign Inc for $21 Billion within a year.
