Pierre Jeanneret and his cousin Charles-Edouard Jeanneret, alias Le Corbusier had a 20 year partnership since 1923. In Paris, they created "The Le Corbusier and Pierre Jeanneret Practise". Together, they designed some of the most extraordinary  works of the 20th century. Some of the famous work together were Villa Savoye ( Clarté building) in Geneva along with Charlotte Perriand in 1927. 

Although the two cousins shared a similar architectural vision, they disagreed on their commitments during the war. Le Corbusier who is highly criticized today for choosing to open a practice in Vinchy during the occupation, while Pierre Jeanneret left to join the French Resistance.

After the war, they reunited in 1950 to work on the monumental construction project of the new capital for the Punjab State, Chandigarh in India. Indian Prime Minister Jawaharlal Nehru wanted a modern city, unrestricted by the traditions of the past and which would become the symbol of modern India. The Swiss-born architect Le Corbusier was selected, at last he could implement his dream of a modern city. Pierre Jeanneret would be the pillar for the project's practical implementation.

The city's construction spanned the 1950's and 1960's and Pierre Jeanneret moved to India, where he lived for 15 years. As the Chief Architect, he oversaw the construction of housing, elementary and high schools, colleges, libraries, healthcare, as well as the laboratories in the Science Blocks and the lecture theatres of the Arts blocks and markets for 15 years. Some of his most famous work would be the Panjab University for the Administration building, the library and the Gandhi Bhawan which was closest to his heart. 

Pierre Jeanneret returned to his home, Geneva in 1965 due to his declining health and passed away in December 1967. According to his will, his ashes were bought back to India which were later dispersed at Sukhna Lake in Chandigarh.
