Professor Emeritus Igor Paul ’60, SM ’61, PhD ’64, an influential professor of mechanical engineering, passed away on Dec. 17, 2023 at his home in St. Petersburg, Florida. He was 87. 

Paul was a member of the MIT Department of Mechanical Engineering faculty from 1964 until his retirement in 2003, and helped to develop the department’s design and manufacturing curriculum, which continues to thrive today. His research interests included product and machine design, safety, and risk analysis; robotics; biomechanics; and dynamic systems modeling. 

A leading expert in product design and safety, with a particular focus on sports devices like helmets, Igor served as an expert witness in many landmark product liability cases. He also contributed to the development of artificial joints and the development of inertial guidance systems for NASA and provided consulting services to a number of area hospitals and medical centers. 

Paul was known for his good nature, quick wit, and pleasant disposition, and his deep passion for teaching. Among the courses he instructed through the years were 2.72 (Elements of Mechanical Design), 2.70 (now 2.007, Design and Manufacturing I), and 2.009 (Product Engineering Processes). He served for many years as the faculty advisor to the student chapter of the American Society of Mechanical Engineers. 

He also co-authored more than 80 publications and won numerous awards in the areas of design, bio-engineering, and education, including the DeFlorez Award for Creativity in Design (MIT, 1960); the Ralph R. Teetor Distinguished Educator Award (SAE); Outstanding Orthopedic Research Award (Orthopedic Research Society); and the Carl Soderberg Distinguished Service Award (MIT, 2003). 

Paul was born on Oct. 28, 1936, in Kharkov, Ukraine, and migrated across Europe during World War II, arriving in the United States eight years later on Christmas Day 1951. After gaining admission to MIT, he earned all three of his degrees in the Department of Mechanical Engineering.

He is survived by his wife, Natasha Paul (Gruzinov); his daughter, Tahisa Southwell of Las Vegas, Nevada; his son, Victor Paul of Zurich, Switzerland; and four grandchildren. He was preceded in death by his parents, Leo and Lily Paul; his sister, Nina Karouna; and his beloved daughter, Tanya Paul.

Outside of his professional achievements, Paul enjoyed tennis, golf, and traveling the globe. After his retirement in 2003, he and Natasha moved from Andover, Massachusetts, to New London, New Hampshire, then recently settled in St. Petersburg, Florida. 

Paul leaves behind a legacy of scientific contributions, dedication to education, and love for his family. 

Richard M. Wiesman ’76, SM ’76, PhD ’83, a professor of the practice in the MIT Department of Mechanical Engineering (MechE), died on Sunday, Jan. 7. He was 69. 

A technology innovator and leader who saw many complex engineering systems reach the marketplace, Wiesman’s work spanned from laboratory development to field deployment. His broad skills in all aspects of automation and robotics — including design, control, communications, locomotion, actuation, sensing, and power — brought a unique perspective to the education of MIT students and made him a tremendous educator, mentor, and colleague.

“Dr. Wiesman’s great enthusiasm for teaching, in parallel with his distinguished industry career, was a wonderful inspiration for our students,” says John Hart, department head and professor of mechanical engineering. “We will miss him very much.”

Wiesman was a lecturer in MechE in the early 1980s and from 2005 to 2007, and was named professor of the practice in 2007. He taught and supervised research in the areas of design, product development, robotics, controls, and manufacturing, and served as co-director of MIT’s Field and Space Robotics Laboratory. In recent years he served on the teaching teams for courses 2.00B, 2.007, 2.008, 2.009, and 2.810, and worked with and inspired many generations of students, including as a 2.009 instructor last fall.  

Wiesman was born on Oct. 7, 1954, to Harold and Elaine Wiesman. He had two brothers, John and Ron, and grew up in Omaha, Nebraska, before coming to study at MIT. Wiesman earned his bachelor’s, master’s, and PhD degrees in MechE at MIT. His doctoral thesis was on high-speed linear induction machines for transportation applications, which led him to work on the U.S. Navy’s Electromagnetic Aircraft Launch System and the Advanced Arresting Gear system.

Wiesman’s work on mobile robots started with the development of a new class of explosive ordnance disposal robots, which grew into a successful business in mobile robots for hazardous ground-based activities — including special robots for internal pipe inspection, robots for warehouse and packing activities, and analysis of robot team characteristics for planetary exploration.

Wiesman worked at Foster Miller/QinetiQ for over 40 years, starting as an engineer and ending his tenure as the executive vice president and chief technology officer. Most recently, he served as a senior fellow for General Atomics and as a member of Arsenal Capital’s Industrial Growth Advisory Board. In 2021, he shared reflections on his career in mechanical engineering with MechE students, telling them in his summation, “I believe you’ve selected an absolutely wonderful career.”

The Institute is also where Wiesman met his wife of 44 years, Suzanne. Together, they took great pleasure in traveling, hiking, snowshoeing, being with friends, and most of all, raising their three children.

Wiesman is survived by his wife; his son Josh and wife Kristina; his son David and wife Haley; his son Ben and wife Emily; and his grandchildren, Elena, John, William, and Julian, in whom he delighted as “Papa.”
