Wind River Systems selected Applied Materials executive Tom St. Dennis as its next chief executive in September 1999. The appointment was announced in trade coverage dated September 7–8, with St. Dennis scheduled to formally take over on September 20, 1999. He succeeded co-founder Jerry Fiddler, who had served as interim CEO after Ron Abelmann resigned in late 1998.
The move placed a semiconductor-industry operator at the head of a 16-year-old embedded-software company seeking growth in Internet-related markets and professional-services consulting.
What was announced
Wind River Systems Inc., headquartered in Alameda, California, named Thomas “Tom” St. Dennis president and chief executive in September 1999. The contemporary EDN report says the appointment was to become effective on September 20, 1999. An alternate EDN version carries a September 7–8 publication date, explaining why archival records can show slightly different announcement dates.
St. Dennis was still an Applied Materials executive when Wind River selected him. The companies were separate businesses; the appointment was an executive move from a semiconductor-equipment company to an embedded-software supplier, not a subsidiary transfer.

Why Wind River was searching for a CEO
Ron Abelmann had resigned as Wind River’s CEO in late 1998. Co-founder Jerry Fiddler then served as interim chief executive while the company conducted a search that the contemporary report described as lasting nearly a year. St. Dennis’s appointment concluded that process and gave Wind River a permanent leader.
The available reporting does not explain why Abelmann resigned, so the succession should not be presented as the result of a specific operational or personal dispute.

Who Tom St. Dennis was
St. Dennis brought a combination of technical training and commercial management. A later Applied Materials biography identifies bachelor’s and master’s degrees in physics from UCLA and describes his progression through regional management, sales, marketing and technology leadership.
At Applied in 1999, he was group vice president and president of the Planarization and Dielectric Deposition Product Business Group. The group comprised three divisions and more than 1,600 employees in the United States and Japan, according to the contemporary EDN account. That scope gave him experience with product strategy, customer relationships, international operations and organizational leadership in a technically demanding industry.

Why an Applied executive appealed to Wind River
Wind River’s interim leadership emphasized St. Dennis’s leadership ability, global reputation, business strategy, marketing experience, customer-relationship skills and organizational management. Those capabilities were transferable even though Applied Materials and Wind River sold different products.
In practical terms, Wind River was recruiting an executive who had managed large technical businesses and commercialized products through international customer channels. That background could support the company’s effort to expand its software business and build a larger professional-services operation. It is a rationale expressed by Wind River at the time, not proof that any single factor determined the appointment’s later results.

- 1.(-Wind Turbine controller-): Wind charge controller can be used for 0-600w wind turbine. It helps to control wind generator charge battery automatically. When the battery is fully charged, brake can be taken effect automatically by the interior circuit. When the battery voltage drops to restore voltage level, wind turbine can recover to charge battery automatically. So wind controller to protect the wind turbine and the battery.
- 2.(-Automaticity-): This wind turbine controller can auto match 12/24 system. Voltage and current limiting are be controlled during recharging to ensure the best charging effect. Meanwhile, it provides the maximum protection to the wind turbine and battery.

Wind River’s business and 1999 strategy
Wind River supplied software-development tools for embedded systems—software used to build and run computing functions inside specialized hardware rather than conventional desktop PCs. In 1999, the company was looking beyond its established embedded-development business toward Internet-related opportunities and professional-services consulting, as described by EDN.
St. Dennis said he intended to execute Wind River’s existing strategy and pursue opportunities associated with what he called the “post-PC era.” That phrase reflects the business language of 1999 and should not be read as a modern description of cloud, edge or IoT markets.

St. Dennis’s career after Wind River
Later company announcements establish the following chronology:
| Period | Role | Evidence |
|---|---|---|
| 1999–2003 | President and CEO, Wind River | Applied Materials announcement |
| 2003 | Executive vice president of sales and customer satisfaction, Novellus Systems | Novellus announcement archived by Lam Research |
| 2005 | Senior vice president, Applied Materials | Applied Materials announcement |
| 2007 | General manager of Applied’s Silicon Systems Group | Applied Materials announcement |
| 2010 | CEO, FormFactor | EDN report |
Applied’s later records also clarify that St. Dennis returned to Applied in 2005, six years after leaving for Wind River; that return should not be confused with his 1999 move.
Why the 1999 appointment mattered
The appointment illustrates how technology companies recruit across adjacent sectors. Wind River did not need a leader with an identical product history to its own; it sought operating scale, technical credibility, customer knowledge and the ability to turn a strategy into growth. St. Dennis’s move from semiconductor equipment to embedded software reflected that broader executive-market logic.
He was Wind River’s CEO from 1999 through 2003. The event is therefore a historical leadership change, not a statement about the company’s current chief executive. For example, Wind River’s 2020 succession announcement identifies Kevin Dallas as succeeding Jim Douglas in a much later period.
