September 15, 2025, represents National Engineers' Day, a significant occasion dedicated to recognizing the vital contributions engineers make to develop the country's infrastructure and driving innovation based on knowledge and expertise.

This observance highlights the essential function engineers serve in constructing a contemporary society, particularly as the nation enters its Techade—a 10 year period characterized by accelerated technological advancement and revolutionary development. In commemoration of Engineer’s Day 2025, here are some major architects who made history contributing to the infrastructure development of their respective field.

Sir M. Visvesvaraya

Sir Visvesvaraya revolutionized India's infrastructure development by implementing groundbreaking engineering designs, forward-thinking strategies, and effective solutions that merged technical expertise with meaningful social benefits. Honored with the Bharat Ratna in 1955, his progressive concepts remain influential for contemporary economic strategists. His significant achievements in this domain encompass several key areas: He created water storage systems such as Osman Sagar and Himayat Sagar while developing comprehensive flood management strategies.

Additionally, Sir Visvesvaraya constructed the Krishna Raja Sagara (KRS) Dam in 1932, establishing what became Asia's most extensive reservoir and revolutionizing agricultural practices in the Mandya region.

Sir M. Visvesvaraya transcended his role as an engineer to become a visionary nation-builder who recognized education and knowledge as fundamental pillars for the country's progress.

His forward-thinking approach led to the creation of key institutions such as Mysore University, the State Bank of Mysore, and the Bhadravati Iron and Steel Works, reflecting his comprehensive outlook toward building a self-sufficient and contemporary India.

He strongly championed industrial growth and modernization, promoting the integration of scientific reasoning into daily life and governmental processes.

His exceptional combination of technical knowledge and leadership skills resulted in his receipt of India's most prestigious civilian award, the Bharat Ratna, in 1955.

Dr. APJ Abdul Kalam

Dr. Avul Pakir Jainulabdeen Abdul Kalam, widely recognized as Dr. APJ Abdul Kalam, was a distinguished Indian scientist, aerospace engineer, and inspirational leader. He earned the beloved title "People's President" due to his significant contributions to science, technology, and India's socio-economic progress.

Serving as Project Director, Dr. Abdul Kalam played a key role in creating India's first domestically-built Satellite Launch Vehicle (SLV-III), which successfully placed the Rohini satellite into near-Earth orbit during July 1980. He supervised the advancement of ISRO's launch vehicle program, particularly focusing on the PSLV (Polar Satellite Launch Vehicle) design. Kalam managed the Devil and Valiant projects, which sought to create ballistic missiles utilizing technology from the successful SLV program. Under Dr. Kalam's guidance, the Integrated Guided Missile Development Program (IGMDP) produced the Agni intermediate-range ballistic missile and the Prithvi surface-to-surface missile, strengthening India's defense systems. He played an essential role in India's 1998 nuclear testing at Pokhran, which showcased India's nuclear capabilities and enhanced national security.

In collaboration with cardiologist Soma Raju, Abdul Kalam created the 'Kalam-Raju Stent,' an affordable coronary device that helped make medical care more accessible to everyone.

Serving as the head of the Technology Information, Forecasting, and Assessment Council and as a distinguished scientist, he guided the nation alongside 500 specialists to develop Technology Vision 2020, which offers a strategic plan for India's transformation from a developing nation to a developed one.

 

Prof. Satish Dhawan

Professor Satish Dhawan, a founding figure in India's space exploration efforts, came into the world in Srinagar on September 25, 1920. This recipient of the Padma Vibhushan was recognized for his expertise across multiple disciplines.

The pilot initiative led by Prof. Dhawan paved the path for establishing state-of-the-art wind tunnel infrastructure at the National Aerospace Laboratories (NAL) in Bengaluru. Prof. Dhawan possessed exceptional leadership capabilities, which he utilized when forming project groups at ISRO. He selected individuals including APJ Abdul Kalam, Roddam Narasimha, and UR Rao, among others, to head initiatives that led to creating SLV-3, India's inaugural launch vehicle, and Aryabhata, the country's first satellite. He also took responsibility for recruiting young, skilled, and dedicated personnel for ISRO. Prof. Dhawan conducted groundbreaking research in rural education, remote sensing, and satellite communications. His accomplishments contributed to creating INSAT, a telecommunications satellite, IRS, the Indian Remote Sensing satellite, and the Polar Satellite Launch Vehicle (PSLV), which positioned India among the leading space-faring countries. Working under Prof. Dhawan's leadership, ISRO worked toward fulfilling Vikram Sarabhai's dream of applying space research to address India's development needs. Even following his retirement, he maintained his focus on public policy matters related to science and technology, especially space technology.

Vinod Dham

Vinod Dham, widely recognized as the "Father of the Pentium Chip," represents a prominent figure in the worldwide technology sector.

Beginning his career focused on non-volatile memory at Intel, he co-created Intel's inaugural Flash Memory technology (ETOX), an innovation that established the foundation for contemporary data storage. Released in the early 1990s, the Pentium processor served as the cornerstone for modern personal computing, securing Intel's market leadership against intense rivalry from major industry players and partnerships. He was instrumental in developing the AMD K6 processor, popularly known as the "Pentium killer," which heightened competition within the global processor marketplace. Dham's strategic expertise was crucial in AMD's emergence as a strong rival to Intel. Subsequently, he established Silicon Spice, a company specializing in voice-over-IP (VOIP) chip technology. Dham's dedication to fostering talent and innovation resulted in his co-founding of NewPath Ventures and Bharat-US Venture Partners. Dham acts as a consultant to the Ministry of Electronics and the Bharat Semiconductor Mission, directing Bharat's initiatives to create a domestic chip production industry. He actively promotes the development of a strong semiconductor ecosystem in Bharat, stressing the importance of decisive, unified efforts to achieve technological independence. In 2025, Dham launched the Vinod Dham Centre of Excellence for Semiconductors and Microelectronics at DTU, his former university. This facility focuses on semiconductor design research, innovation, and education, seeking to prepare a new wave of engineers and decrease Bharat's dependence on foreign technology. Dham's goal is to position Bharat as a worldwide semiconductor industry leader, supporting national programs like Atmanirbhar Bharat.

Dr. Verghese Kurien

Dr. Verghese Kurien, commonly referred to as India's "Milkman" and the "Father of the White Revolution," was a prominent Indian social entrepreneur who spearheaded India's transformative White Revolution.

Kurien is recognized as the mastermind behind India's white revolution, a movement that transformed the nation into a self-reliant dairy powerhouse and the globe's top milk producer.

His groundbreaking cooperative model developed in Anand became the catalyst for expanding the white revolution throughout India's dairy industry.

The Anand Model represents a cooperative framework enabling farmers to control their own supply chain - from procurement and processing to marketing their products - while receiving professional guidance.

Its effectiveness stems from empowering farmers through democratic participation, where elected representatives supervise professional management operations.

This framework encompasses farmer-controlled assets including cooperative societies, dairy processing facilities, feed manufacturing plants, and distribution networks, creating direct connections between producers and end consumers.
