[1] Prewitt's art career started over fifty years ago as a teenager creating and selling his works then expanded to developing computer technology and racing.

He has produced art in a wide array of genres and mediums, including oils, acrylics, pencil drawings and photography.

His works are displayed in many public and private venues, seen in movies such as Steven Soderbergh's Mosaic on HBO, and found in videos, advertisements and high-end restaurants, and are available from a limited number of galleries.

In the 1970s and 1980s he was one of the early creators[5] of personal computer products, developing popular software and hardware while helping build a new industry.

He created the technology and trademarked Hotplug, the computer industry's standard method of replacing computer system components without the need for stopping or shutting down key parts such as disk drives, disk controllers or host adapters and power supplies.

Prewitt's first patent details were disclosed in 1987 in the United States[7] and Europe[8] related to development of the technology, however, the filings were not completed.

[9] Another trademark Prewitt created in the late 1970s and registered in the 1980s was "CORE",[10] used to identify computers and related products.

In 2006, after Prewitt's company was sold and the registration use was discontinued, this trademark was adopted by Intel to market their computer processors.

Skilled[6] in computer programming and engineering, Prewitt founded and managed a number of technology firms.

The largest and best known was Core International, a developer of disk array, computer data storage and backup products.

Prewitt learned how to fly a plane, soloed at 16 and shortly thereafter earned his Private Pilots License at the youngest age allowed.

[5][6] As a teenager, Prewitt learned sailing, fishing, boating and scuba diving and developed skills in mechanics, engineering, electronics, navigation and construction.

[5][6] After graduating high school, Prewitt continued building boats, managing his business and began to focus on computer programming.

In the early 1970s, Prewitt dreamed of designing, building and selling a generation of small business computers with a price tag much less than the going rate of $50,000.

Prewitt's father joined the U.S. Air Force underage at 13 years old using his older brother's ID and then switched to the U.S. Navy at 17 serving in World War II and Korea.

[1] Prewitt attended All Souls Catholic School (1960–63) in Sanford, Florida, until 3rd grade while his father served in the military.

After high school, Prewitt attended Daytona Beach Community College (1972–76) studying business and computer science but left without earning a degree.

Prewitt's final jobs where he was employed by someone else were as a lab assistant helping students in his college and as a computer programmer for a company providing business applications on mainframes and minicomputers.

[5][6] He used the manufacturing part of the business to build electronics, computers and fiberglass boats from 13' fishing runabouts to a 40' houseboat.

He had customers that were located from mid to south Florida in manufacturing, hotel, service, legal, medical, construction and agricultural industries.

Initially Core was created as a for-profit association of owners and operators of small IBM computers.

Prewitt built his first computer storage product for the IBM 5100 series because the machines did not have hard disk drives.

In 1986, Inc Magazine selected Core as 21st in their annual list (Inc. 500) of the 500 fastest-growing private companies in the U.S. and were building computers and related products.

By 1990, Core was well known as an industry leading developer of disk array, computer data storage and backup products.

[6] COREtest became the industry standard[15] and most often quoted benchmark used to test, evaluate and compare performance of hard disk drives.

[5][6] Many[6] of Prewitt's products were the first of their kind, had no direct competition and were widely regarded for their superior[16] performance and reliability.

Prewitt's art is in a wide array of genres and mediums including oils, acrylics, pencil drawings and photography.

Prewitt is philanthropic with many of his artworks by donating to nonprofits who often auction his art to raise funds for their organizations and display his works.

[1][21] In March 2009, one of the corporations Prewitt manages, bought for a real estate investment [22] a house in Park City, Utah, that had belonged to Massachusetts Governor Mitt Romney[23] since 1999.
