The Childhood of bill gates

  • October 28, 1955, William Henry Gates ІІІ was born.

  • Born into a family with a rich history in business and politics.

  • Gates grew up in Seattle, Washington with his sisters.

  • His father, William H. Gates ІІ is a Seattle attorney.

  • His mother, Mary Gates who passed away was a school teacher, University of Washington regent, and chairwoman of united Way international.

  • Gates attended private elementary school in Seattle.

  • During his stay in elementary school, Gates revealed his interest in software and began programming computers at the age of 13.

  • Gates surpassed all of his felloe students abilities in practically all subjects, especially the math’s and sciences.

  • His parents recognized his intelligence and decided to enroll him at Lakeside, which is a private school known for its intense academic environment.

  • Early in Bill Gates’ childhood, it was obvious that he inherited the aspiration, cleverness, and competitive spirit to program computers.

Bill Gates

Early Accomplishments

  • In 1975, Bill Gates and Paul Allen were attending Harvard University when they made their first significant accomplishment in the world of personal computers.

  • Paul Allen stumbled across an issue of popular Electronics, featuring the first minicomputer to rival commercial models, the Altair created by Ed Roberts.

  • The Altair was an incredibly elementary, yet ground-breaking device that raised the hopes of future programmers.

  • Gates and Allen determined to implement the BASIC computer language on the Altair.

  • Gates and Allen joined Roberts and successfully implemented BASIC on the Altair.

  • From that point on, Gates and Allen were given jobs at Robert’s Micro Instrumentation and Telemetry Systems (MITS) computer company.

  • In July 1975, Allen and Gates formed a business partnership called Microsoft.

  • Later on that year, Microsoft made an agreement with MITS to allow them to distribute their software, while not selling it to them.

  • Years later, tension mounted between Microsoft and MITS, as Roberts wanted Gates and Allen to work for Altair.

  • While the industry demanded more advanced software, Gates and Allen turned to other microcomputer manufacturers.


Paul Allen

Albuquerque Group

  • A serious road block hindered Microsoft as their revenue slowly began to trickle down.

  • Gates discovered that club members were copying and freely distributing their software throughout the country.

  • Gates wrote two letters to the clubs proclaiming his stance on the situation.

  • Following a discussion at a computer seminar, Gates closed the issue and agreed to move on.

  • Months later, Gates and Allen hired several young programmers and began distributing to respectable companies such as General Electric and Motorola.

  • After this, they established their first office in Albuquerque, New Mexico, where Microsoft began to take off an a powerhouse.

The Growth Of Microsoft

  • IBM played a crucial role in turning Microsoft into a superpower in the computing world.

  • because of the changing market, IBM became increasingly interested in microcomputers.

  • After wanting to enter the market themselves, IBM knew that they needed help from an outside company.

  • Since Microsoft’s name kept turning up, and sales numbers were so high, IBM sought out Bill Gates.

  • After a couple of meetings, IBM revealed to Gates that they wanted to release a little more than half a year a personal computer capable of running popular programs.

  • Microsoft agreed and said that, given the specifications, they could do it. IBM called this plan “Project Chess”.

  • Microsoft’s first step was finding the operating system they would use for the 16 bit microprocessor.

  • Microsoft ended up buying the rights to an operating system called QDOS, or Quick and Dirty Operating System.

  • Once Microsoft pulled all of this together, they were able to convince IBM that they were the right people for the job. On November 6, 1980 Microsoft signed a contract with IBM.

  • Bob O’ Rear was the man in charge of developing MS-DOS. The new named for QDOS.

  • In February 1981 MS-DOS ran on a prototype for the first time.

  • IBM made MS-DOS the official system of the IBM PC.

  • IBM announced their new microcomputer on August 12, 1981.

  • Microsoft then entered software market. They released MS-DOS.

  • The success of MS-DOS had a large impact on Microsoft and in turn on the field of personal computing.

  • By 1984 MS-DOS clearly dominated the field.

  • In 1986 Microsoft announced that half of its annual revenues came from sales of their operating system.

  • This gave Microsoft financial stability. This stability allowed Gates to start developing other applications, such as Microsoft Word and Multiplan.

  • These programs, beginning with MS-DOS, made Microsoft into a superpower, and changed the face of business and personal computing.

  • As of last year Microsoft’s net revenue was $28.37 billion.

  • Computers worldwide now use Microsoft programs and its chairman Bill Gates is the richest man in the world.

The Windows Era

  • Bill Gates proposed a creation of an interface manager to replace MS DOS.

  • This interface would eliminate problems and be graphical and user friendly.

  • This proposal became known as Windows and would have failed if not for the dedication of Bill Gates.

  • The goal of the project was to make the interface independent of the hardware, workable in graphics mode, and standardize the appearance of applications.

  • Work began on this project in September of 1981, by 1983 it had its official name of Microsoft Windows.

  • In 1984, Bill Gates stated that Windows would be operating on 90% of MS DOS PC’s.

  • This announcement is one that Microsoft would live to regret.

  • The release date of Windows was pushed back several times due to problems. Other companies that wrote programs for Gates were not happy.

  • In the summer of 1984, Microsoft did a company reorganization in the hopes of completing Windows.

  • While Windows was being completed IBM released its Top interface. The product failed like most of its kind at the time.

  • Windows was no Microsoft’s top priority and a team of thirty people were working twenty-four hours a day, seven days a week until its completion.

  • Finally in November 1985, Microsoft Windows was released.

  • Initial market reaction to the interface was mild. Computers could not adjust to it and the interface ran slow and had few programs to run on it.

  • Program publishers lost interest in creating programs for Windows.

  • Despite all the problems Microsoft faced, Windows series went on to become Microsoft’s best selling software.
