In Memoriam: H. Reed Wiegle

Remembering H. Reed Wiegle: ISA Standards Pioneer and Automation Visionary

Celebrating the life and legacy of an industrial automation leader who shaped nuclear power standards and batch control systems.

Early Influences and Engineering Education

H. Reed Wiegle passed away on June 8, 2025, at age 81. His early inspiration came from his uncle, Charlie Linnert. Linnert worked on the Manhattan Project as a nuclear engineer. He also developed control rod drives for the USS Nautilus submarine. Consequently, Wiegle pursued electrical engineering at the University of Pennsylvania. He graduated in 1965 and earned his master’s degree in 1971. His thesis focused on the Muddy Run Pumped Storage Station.

Professional Career in Power Generation

Philadelphia Electric Company hired Wiegle after graduation. He worked across multiple power generation domains during his career. His experience included substations and fossil fuel plants. He also worked in hydroelectric and nuclear generating stations. Additionally, he contributed to quality management systems. This diverse background gave him comprehensive industry perspective.

After retiring from Philadelphia Electric, he began consulting work. He joined Canus Corporation and later the Shaw Group. His consulting took him to South Africa to study modular reactors. He also participated in nuclear plant restart teams. These included Comanche Peak in Texas and Davis-Besse in Ohio.

Significant Contributions to Industrial Automation Standards

Wiegle made substantial contributions to ISA standards development. He served on the ISA Standards and Practices Board until 2004. He dedicated particular attention to the ISA67 committee. This group focuses on nuclear power plant standards. His work earned him an ISA Service Award in 1992.

In 1997, he received an ISA Achievement Award. This recognized his pioneering work on ISA-TR88.0.03. This technical report explored recipe procedure formats for batch process automation. It built upon the influential ISA-88 standard for batch control systems.

Technical Legacy in Batch Process Control

Wiegle’s work on ISA-88 standards impacted modern industrial automation. Batch process control relies heavily on these frameworks. They provide models and terminology for automated manufacturing systems. The standards enable consistent implementation across different platforms. They also facilitate integration between control systems and enterprise software.

Key aspects of his standards work include:

  • Recipe management and procedure presentation formats
  • Nuclear power plant instrumentation standards
  • Internet-based standards development methodologies
  • Batch control system architecture definitions

Personal Passions and Mechanical Aptitude

Wiegle possessed remarkable mechanical problem-solving skills. He could understand and fix almost any broken device. He enjoyed operating heavy equipment on his property. Weekend tractor sessions brought him genuine satisfaction.

Reed Wiegle's diverse interests included vintage cars and foxhunting

His personal interests reflected his engineering mindset. He loved vintage automobiles and auto racing. He attended the Indianapolis 500 thirty-eight times,and also participated in foxhunting with the Kimberton Hunt organization. Additionally, he competed in three marathons and organized running events.

Industry Impact and Lasting Influence

From World of PLC’s perspective, Wiegle’s work remains highly relevant today. Modern industrial automation still builds upon ISA-88 principles. Batch processing systems in pharmaceuticals and chemicals use these standards. They also influence food and beverage manufacturing automation. The frameworks ensure consistent control system implementation.

His nuclear power standards work also maintains importance. Nuclear facilities worldwide continue using ISA67 committee outputs. These standards help ensure safe and reliable nuclear operations. They cover instrumentation and control systems critical to plant safety.

Modern Applications of Wiegle’s Work

Today’s industrial automation professionals benefit from Wiegle’s contributions. Modern batch processing systems implement ISA-88 concepts. These systems often integrate with sophisticated control infrastructure. Proper implementation requires understanding both standards and practical control systems.

For engineers working with batch processes and control systems, understanding these standards is crucial. When designing or upgrading batch automation systems, consider exploring compatible control system solutions that support ISA-88 implementation. Our platform provides resources for effective batch control system design.
