The Legacy of Yvon Macq: Transforming Macq into a Pioneer of Innovation 


When Yvon Macq took over his family’s business in the 1970s, he ushered in a transformative era, marking the beginning of the company’s second generation. His vision for Macq was grounded in innovation, standardization, and automation, which became the foundation of the company’s philosophy. Recognizing the potential in the flourishing field of electronics, Yvon shifted Macq’s focus from tailor-made projects to series production, ensuring scalability and sustainable growth.

In 1968, under Yvon’s leadership, Macq developed the first European Programmable Logic Controller (PLC), the PIP. This groundbreaking invention positioned Macq as a leader in automation. Over the following decades, the PIP series evolved significantly, with each iteration reflecting advancements in technology. The release of the PIP4000 in 1972, the first 16-bit processor PLC, showcased Yvon’s commitment to innovation and keeping Macq ahead of global competitors.

Yvon’s strategy extended beyond industrial automation. In the 1980s, he identified new opportunities in the building sector, equipping major infrastructures like the Palais du Heysel in Brussels with advanced automation systems. This diversification led to Macq’s involvement in landmark projects, including the supervision of the Liège tunnel and infrastructure automation for roads, tunnels, and waterways. These projects cemented Macq’s reputation as a reliable partner for large-scale, complex systems.

In the 1980s, recognizing the company’s growth needs, Yvon relocated Macq’s headquarters to Evere, Brussels. The new site not only provided space but also reflected Yvon’s dedication to sustainability, with gardens, orchards, and rooftop beehives enhancing employee well-being.

Yvon’s foresight was also evident in his embrace of emerging technologies. By adopting Apple’s revolutionary mouse interface and UNIX platforms in the 1990s, he ensured that Macq’s supervisory computers, such as OBViews, were at the forefront of technological advancement. These systems revolutionized visualization and control, making Macq a key player in industries ranging from cement and chemicals to transportation and agri-food.

Throughout his career, Yvon Macq guided the company through a period of extraordinary technological evolution, ensuring its ability to adapt and thrive. As the 2000s approached and competition in automation intensified, Yvon and his son François pivoted Macq toward a new growth market: mobility. This strategic shift laid the foundation for Macq’s continued success in today's modern era.

Yvon Macq’s leadership is a testament to his entrepreneurial spirit, innovative mindset, and unwavering commitment to excellence. He not only solidified Macq’s legacy but also paved the way for its future as a leader in automation and mobility solutions.
