The Volta Laboratory became an experimental facility devoted to scientific discovery, and the very next year it improved Edison's phonograph by substituting wax for tinfoil as the recording medium and incising the recording rather than indenting it, key upgrades that Edison himself later adopted.
In partnership with Gardiner Greene Hubbard , Bell helped establish the publication Science during the early s.

At the time of the organization of the Bell Telephone Company as an association also known as the Bell Company , on July 9, , as a joint stock company in by Hubbard,   who soon became its trustee and de facto president, 5, shares in total were issued to: .
The Bell Telephone Company was incorporated in Massachusetts on July 30, with 4, shares of stock. American Bell's outstanding stock rose to , shares by May Two days after the company's formation, on July 11, , Bell married Hubbard's daughter Mabel Gardiner Hubbard ,  and made a wedding gift of 1, shares of his allotment to his new wife, keeping only 10 shares for himself.
Bell and his wife left not long after for a tour of Europe that lasted over a year, during which time Mabel left her shares with her father under a power of attorney , allowing him to become the new company's de facto president.
Both Hubbard's and Sanders' roles in the newly born company were pivotal to its early survival and its eventual growth to become a corporate giant.
Hubbard's very early structuring of its telephone service by leasing, instead of selling telephones, was critical to its success. He based his decision on the previous legal work he performed for the Gordon McKay Shoe Machinery Company, where its shoe sewing machines were leased, not sold, and royalties also had to be paid to the Gordon McKay Company based on the numbers of shoes produced.
Hubbard insisted that leasing was the better option, even if it significantly raised the need for initial capital expenses.
Not long after the National Bell Telephone Company was established, it required substantial new capital in order to maintain its majority share ownership of its affiliate telephone companies and to provide further funds for expansion of its overall telephone infrastructure.
Of the Bell Company's original shareholders, Thomas Watson resigned his position in with his shares bringing him up to the status of a millionaire, thereafter living a colourful life as a Shakespearean actor and later as a shipyard owner and ship builder—always retaining his friendship with Bell.

Pivotally, late in the evening moments after the main group of tired judges and newspaper reporters had quickly looked over and derided Bell's telephone display, Emperor Dom Pedro, who was straggling, entered the fair's Education Building where Bell's two displays were located.
As the main group started moving on to the next exhibit to be reviewed, Dom Pedro came upon the displays and called out to Bell in his booming voice: "What are you doing here?
Tired and hungry, they hardly looked at the telephone, made some jokes at Bell's expense, and wanted to leave the exhibition quickly when suddenly, Dom Pedro II, Emperor of Brazil from to , with his wife Empress Theresa and a bevy of courtiers, entered the room.
Dom Pedro had once visited Bell's class of deaf-mutes at Boston University and initiated the first Brazilian school for deaf-mutes in Rio de Janeiro.
The judges stayed the next three hours with Bell. Bell's telephone became the star of the centennial Few paid much attention to Bell, tinkering with his crude instruments.
