Ken Olsen the Man

As an inventor, scientist, and entrepreneur, Ken Olsen is one of the true pioneers of the computing industry.
Bill Gates

Kenneth “Ken” Harry Olsen (1926-2011) was born in Bridgeport, Connecticut in 1926. While fixing radios in his basement during his early years, he gained a reputation as a “neighborhood Edison.” After graduating from high school, Olsen enlisted in the Navy in 1944 and served until 1946 as a radio technician. In 1950, he graduated from MIT with a B.S. in electrical engineering and then received an M.S. in electrical engineering, again from MIT, in 1952. 

After graduating with his B.S., Olsen headed to Finland in pursuit of love. He married Eeva-Liisa Aulikki Valve, whom he’d met previously, on December 12, 1952 in Lahti, Finland. Together they welcomed three children, daughter Ava and sons Glenn and James.

On top of his involvement in the tech world, Olsen was devoted to his faith, serving as a deacon and as the director of religious education in the 1950s and 1960s at Park Street Church. He was also a philanthropist and outdoorsman. The Olsen we know was shaped by his experiences, hobbies, and attitudes outside of the tech world. In this exhibit you will get acquainted with Ken Olsen the man, Ken Olsen the tech guru, and learn how his legacy has played out at Gordon and in the world.

U.S. Navy Hat

Olsen served in the Navy from 1944-1946 as a radio technician. This hat belonged to Olsen while he served in the Navy.

Notice of Classification

Olsen’s Notice of Classification card. The only date listed is from June 19, 1946, presumably when he left the Navy. The Notice of Classification card was a part of the draft process. The Class number of 1-C meant that Olsen was a “Member of the Armed Forces of the United States, the Coast and Geodetic Survey, or the Public Health Service.” The DISC meant that he was honorably discharged from military service.

Flight Log

Apart from his computer pioneering and his career as a Navy radio engineer, Olsen was also a pilot. This is a sample page from his October 1969 – July 1972 flight log. There are three other logs held in the collection. Occasionally, Olsen would take part in local search and rescues and note it in his log books.

Glenn Rifkin & George Harrar

After working at MIT’s Lincoln Laboratory, which worked on designing and building computers for air defense application, Olsen and colleague Harlan Anderson founded Digital Equipment Corporation (DEC) with only $70,000 in capital in 1957. DEC found its home in an old mill building in Maynard, MA, but soon had employees in 97 countries. By 1988, DEC became an $11 billion company, the second largest computer company just behind IBM, the 38th largest industrial company in the Fortune 500 and the 13th most profitable.

With patents for saturable switches, diode transformer gate circuits, line printer buffers, and an improvised version of magnetic core memory, Olsen led the revolution of the mini-computer with machines like the PDP-8, PDP-11, VAX, and VT100. After having served as president and CEO of DEC for 35 years, he resigned in 1992.

Upon resigning from DEC, Olsen could not stay away from the tech world and founded Advanced Modular Solutions, Inc. in 1995. He served as the company chair until it ceased operations in 1999.

American/Dutch Flag Pin

DEC quickly became an international company with offices in France, Sweden, Norway, China, Turkey, and more! This pin includes an American flag next to a Dutch flag and has the Digital logo on it.

Magnetic Core

Magnetic core memory was the predominant form of random-access computer memory from about 1955 – 1975. Each little "donut" (iron ferrite torus or ring) is called a "core" and stores one bit (0 or 1). The bit is stored as a direction of magnetization (that is, magnetized one direction means 0, and the other direction means 1). The wires running through the cores are used to select which ones to access, and to either read or write their contents. Olsen holds a patent for magnetic core memory.

Signal Core

This round, silicon wafer was most likely used to help test and understand circuit design and manufacturing for the process that made the wafer. It was built and then used to measure how the wafer worked. Information garnered from testing it would then be used to improve both the design and manufacturing subsequent "real" (useful in products) chips with the same wafer (chip) fabrication process.

Circuit Board

A circuit board, which appears to be a memory board, with integrated circuit memory chips (the array of black chips). There are also interface chips (gold, near the connector edges on the bottom) and various other control and support chips around the edges, plus lots of resistors and capacitors to help it all work electronically.

PDP-8

The PDP-8 was the first commercially successful minicomputer, triggering the minicomputer industry, and cost only $18,000. At the time, it was a bargain! It ended up selling 50,000 units and launched DEC into the big leagues. 

PDP-8/1 Panel

PDP-11

Introduced in 1970, the PDP-11 sold for $10,800. This machine and its succession of follow-up models sold 250,000 units.

VT100

A VT100 terminal from the Olsen Collection. Typically, the keyboard would rest under the lip of the terminal, but this case isn’t wide enough for them to fit that way, so the keyboard is located on top of the terminal. The elegant styling and design drove it to become an industry standard and it was soon followed by VT200 and VT300 terminals.

A large grey early laptop. The top part of the open computer shows a small black screen in the middle of the top. Half of the bottom is taken up by a full keyboard including a full number pad. The right, top half of the bottom of the computer has an inset mousepad.

DECpc333

The DECpc 333 Portable computer, manufactured by DEC from 1991-2004, came complete with Microsoft Windows and an integrated mousepad. It also was able to be placed into a framework that turned it from a portable computer to a network computer. The DECpc 333 boasted a luxurious 4 MB of memory and a 60 MB hard drive as well as a 33 MHz 386 processor with cache memory. It only weighed 11 pounds and the battery lasted for 3 hours!

VAX

VAX (Virtual Address Extension) debuted in 1977 and was a breakthrough architecture that allowed DEC to create a family of computers that could grow expansively into the 1990s.

Ken Olsen's Legacy

The Christian and the scientist should always seek the truth.
Ken Olsen

The legacy of Ken Olsen has a special place at Gordon College. In 2003, Olsen and his wife, through his philanthropic Stratford Foundation, donated a large sum of money to fund the Ken Olsen Science Center. It is the first, and only building, Olsen allowed to be named after himself.

Bill Gates wrote, in 2006, “He was also a major influence in my life and his influence is still important at Microsoft through all the engineers who trained at Digital and have come here to make great software products.” Olsen’s entrepreneurship in the tech world is still felt to this day.

Friend and fellow Gordon Board member, Tom Phillips, explained how Olsen “was a major philanthropist who did his giving quietly, never seeking recognition of thanks.” This is evident in the numerous plaques, awards, and mementos given to Olsen over his career from outdoor groups to Gordon College.

Olsen was also interested in the preservation of computer history. The first exhibits of the Digital Computer Museum were displayed in the lobby of DEC in 1975. Later, the Computer Museum opened its doors in 1984 and was located on Museum Wharf in Boston. After it closed in 1999, the collection was incorporated into the Computer History Museum in Mountain View, CA which opened in 2002.

Bill Gates Letter

Letter to President R. Jud Carlberg from Bill Gates from April 17, 2006. In response to a letter sent by Gordon College asking Gates or the Gates Foundation to donate a large gift to the Ken Olsen Science Center for the “Heart of Discovery” campaign, Bill Gates sent this letter to then president R. Jud Carlberg. While the request for a gift was not in line with the foundation’s goals, Gates still sent a personal letter outlining how influential Olsen had been in his own life and career.

Text of letter: 

April 17, 2006

R. Judson Carlberg
President
Gordon College
255 Grapevine Road
Wenham, MA 01984

Dear President Carlberg:

An inventor, scientist and entrepreneur, Ken Olsen is one of the true pioneers of computing. He was also a major influence on my life. My interest in software was inspired by the DEC computer I first used as a 13-year-old at the Lakeside School. Later, Paul Allen and I used the PDP-10 to create the first version of the BASIC language software for the personal computer. We also enjoyed working with Ken's company as it helped us create the personal computer industry. 

Ken's influence is still important at Microsoft through all of the engineers who trained at Digital and have come here to make great software products. The passion and discipline that these engineers learned at DEC are the qalities that we also admire and reward.

It's a pleasure to honor Ken for his contributions to the field of computing and his role in helping to create the computer industry.

Sincerely,
[Bill Gates signature]
