A. P. J. Abdul Kalam vs Gro Harlem Brundtland

Kalam led the development of India's first indigenous satellite launch vehicle (SLV-3) under the SLV-3 project at ISRO. The first experimental flight of SLV-3 in 1979 failed, but the second in 1980 successfully placed the Rohini satellite in orbit, making India a spacefaring nation.

As Chief Scientific Adviser to the Defence Minister, Kalam played a key role in India's second nuclear weapons test at Pokhran. The tests established India as a nuclear weapons state, leading to international sanctions but also strategic autonomy.

Kalam published his autobiography 'Wings of Fire', detailing his early life, work at ISRO and DRDO, and his role in India's space and missile programs. The book became a bestseller and inspired millions of young Indians to pursue science and public service.

Kalam was elected as the 11th President of India with support from both the ruling NDA and opposition parties. He served a single term from 2002 to 2007, becoming known as the 'People's President' for his accessibility and focus on youth and education.

Brundtland became Norway's first female Prime Minister in February 1981, leading a Labour Party government. Her first term lasted only eight months.

Brundtland chaired the UN World Commission on Environment and Development, which produced the 1987 report 'Our Common Future'. This report defined sustainable development.

Brundtland returned as Prime Minister in May 1986, serving until 1989, and again from 1990 to 1996. Her governments implemented social reforms and environmental policies.

Brundtland served as WHO Director-General from 1998 to 2003. She focused on public health issues including tobacco control, HIV/AIDS, and malaria.
