It's time, once again, to introduce you to the new inductees into the Process Automation Hall of Fame. It's a truly international group this year. This year's inductees are John Berra, former chairman of Emerson Process Management, Sigurd Skogestad, professor of chemical engineering at NTNU, Trondheim, Norway, and Maurice Wilkins, former Honeywell fellow, WBF chairman and now vice-president for global marketing services at Yokogawa Electric Corp. It is a diverse and eclectic group, as you can see, but there are themes that run through the lives and careers of all three.
These masters of the process automation arts have come to the field in sometimes unusual ways. Automation is a multidisciplinary set of skills, and these skills are hard to acquire in any one place, be it university, trade school or on-the-job training. These three men managed to acquire their exemplary skills and then work their entire careers to extend the skills and the reach of automation in manufacturing and especially in the process industries.
The Business Visionary
"I graduated from Washington University in St. Louis with a degree in system science in June of 1969," says John Berra, former chairman of the board at Emerson Process Management. "At that time, there were two paths you could follow with this sort of degree—aerospace and process control. I interviewed with many companies and came to the conclusion that the space program wasn't going to be as active once a man walked on the moon. So I decided to join Monsanto as an instrument engineer."
Berra worked in the corporate engineering group at Monsanto and received excellent training in what process control was all about. Monsanto's training program of that era has produced a significant number of inductees into the Process Automation Hall of Fame. Berra's first projects were pneumatic instrumentation and some very early analog electronic control loops.
"Monsanto was good," he says, "but I wanted to move faster, so I took a job with J. F. Pritchard, an engineering contractor in Kansas City. I learned a lot there and got to spend time in the field on start-ups. I spent a lot of time ringing out wires!"
From there, Berra took a sales engineering job at Beckman Instruments (now Beckman Coulter Inc., www.beckmancoulter.com) and then joined a company called Rosemount (now the Rosemount Measurement Division of Emerson Process Management, http://www2.emersonprocess.com), which had some radical new pressure-sensing technology.
"The rest, as they say, is history," Berra recalls. "I grew up with the company and was promoted several times before becoming the president of Rosemount."
When Emerson, which had acquired Rosemount just a few months after Berra joined, decided to purchase Fisher Controls from Berra's alma mater, Monsanto, Berra became head of the combined Fisher and Rosemount controls business, then called Fisher-Rosemount.
"We ultimately launched DeltaV during my time as president," Berra says modestly. Other Emerson employees, though, recount stories of his deep and intense involvement in the design and creation of DeltaV, which became the model for the second generation of DCS products worldwide, and one of the most successful.
At the same time, Berra was responsible for the development of two of the most successful digital communications busses in process automation. "I am a geek at heart," he says.
First, under his direction, Rosemount developed HART, which has now over 30 million devices installed. Then, after personally working with the ISA SP50 standard committee, he helped launch (and became chairman of) the Fieldbus Foundation (www.fieldbus.org)—which is, especially in the petrochemical industry, growing as a powerful vendor-non-specific communications and control platform.
Berra has been a champion of the independent standards movement, personally in his involvement in ISA standards, as well as in his role as business leader providing the impetus for Emerson's involvement in standards work.
After Rosemount developed the HART protocol as a proprietary technology, Berra led the development of the HART Communication Foundation (www.hartcomm.org), and deeded the patents on the HART technology over to this not-for-profit organization. "The HART protocol was conceived at an offsite meeting that I chaired," he says.
