Marthe Rosine accompanied her husband for his first visit to the island on December 3, 1964, at the invitation of the Cuban government, to give keynote lectures and organize a course at the university, the Prensa Latina news agency reported.

The main contribution to science of the French physicist and chemist born in 1903 was related to agriculture and cattle raising and was worldwide known for his theory on intensive grazing, a topic he tackled in abundant bibliography.

Voisin, who died from a heart attack on December 21, 1964, was buried in Havana, and from then on Marthe Rosine began a lasting relationship of friendship and love with Cuba, where she traveled on many occasions.

In 2003, she attended the activities scheduled in Cuba for the centennial of the birth of her husband, whom she also worked with.

The burial of Marthe Rosine Voisin will take place on Friday, January 6, in Arques la
bataille, Seine-Maritime, where she lived until her death.
