Dr. Wendell Beck Sander is an American engineer and one of the first employees of Apple Inc.

Early life and education

Wendell Sander was born in Donnellson, Iowa in 1935. He received a B.S., M.S., and Ph.D. in electrical engineering from Iowa State University in 1956, 1962, and 1963, respectively.

Career

Sander joined Gilfillan in 1956 to work on missile telemetry systems. In 1958, he began work on hybrid computer and display system design at Tasker Industries in Van Nuys, California. In 1964, Sander joined Fairchild Semiconductor, where he spent 13 years. He became the head of the Complex Array Engineering section of the Digital Integrated Electronics Deptartment developing early Gate Arrays and Semiconductor Memory leading to the Illiac IV Semiconductor Memory system. He then became head of the Memory Research Department designing a Bipolar DRAM.

Apple Computer

He was hired in August 1977 as the newly-incorporated Apple Computer's 16th employee and first staff scientist. Later Steve Wozniak signed the Apple-1 and added the most unique dedication of all known Apple-1: 'To Wendell, a most incredible engineer! Woz. Apple would not have happened without you!'.

Sander also recommended fellow Iowa State graduate Thomas Whitney for the engineering department. The two worked on the Apple II series. Whitney became Executive Vice President of Engineering and focused on recruiting while Sander began designing the Apple III. Sander collaborated with Bob Bailey of Synertek to consolidate Steve Wozniak's Disk II floppy disk controller into a single chip, commonly called the "Integrated Woz Machine", but also known as the "Integrated Wendell Machine". Macintosh team member Andy Hertzfeld considered Sander one of Apple's best engineers.

The Apple III project was code-named "Sara" after Sander's daughter. The specifications were defined by a committee and Sanders was given 10 months to implement the project. Jobs oversaw details of the design, such as the omission of a cooling fan because it would have been "too noisy and inelegant". Many Apple III units began malfunctioning after its initial release in 1980. The early units had unreliable RAM board connectors that caused intermittent failures. Sander stated that the Apple III had been rushed to market 6 to 9 months too early. Whitney was fired from Apple in 1980 and Sander also left the company in August 1982.

Wendell Sander's Apple-1

Dr. Wendell Sander purchased an Apple-1 (listed as Apple-1 #9 in the Apple-1 Registry) and Apple Cassette Interface from a Byte Shop at Blossom Hill Road in South San Jose along with the needed transformers and a Decwriter Keyboard in July or early August 1976. He modified the Apple I computer, with which he wrote a Star Trek game that impressed Apple Computer Company co-founder Steve Jobs.

1985–2005

In 1985, Sander and other former Apple engineers then formed a technical design firm called The Engineering Department in Campbell, California. In 1990, Sander joined General Magic as a fellow providing technology guidance in the development of PDAs.

Apple Inc

In July 2005, Sander returned to Apple to work for his son Brian Sander, also a graduate of Iowa State and a young executive at Apple Inc.; the two collaborated in engineering the circuitry of iPods and iPhones. The elder Sander was responsible for developing the volume controls on Apple's EarPods and was recognized as a Distinguished Engineer, Scientist or Technologist (DEST). He received 115 patents.

After 2010

After retiring from Apple in August 2010, Sander assisted the History San José organization in restoring an Apple I computer in their Perham Collection to working order.
