He was also known for his portraits of famous artists, writers, and intellectuals, including Pablo Picasso, Salvador Dali, Jean-Paul Sartre, and Albert Camus.

From 1952 Almásy worked on behalf of United Nations institutions such as UNICEF, World Health Organization[10] and UNESCO,[11][12] for which he traveled as an accredited employee.

[16][17][18][19] He was a founding member along with Albert Plécy of the photographic group Gens d'Images that annually promotes the Niépce Prize and Prix Nadar.

[20] In 1963, Argentina issued a postage stamp for the fight against hunger featuring one of his photographs, and in 1965, he published "Le monde a thirst", a report on the lack of water in the world.

In 1995, Paul Almásy sold his color photographs to Branded Entertainment Network (Corbis), the image bank founded by Bill Gates.

Over the decades, he made interviews and reports with important people of contemporary history such as Menachem Begin, Nikita Khrushchev, Dwight D. Eisenhower, Charles de Gaulle, Benito Mussolini, Jawaharlal Nehru and the Shah of Persia Mohammad Reza Pahlavi.

Almásy has taken remarkable portraits of many other personalities from public life, which have entered the collective memory - artists of various provenance are to be mentioned here as examples: Salvador Dalí,[25] Alberto Giacometti,[26] André Breton,[27] Colette, Jean Cocteau,[28] Jacques Prévert,[29] Man Ray, Romy Schneider[8] and Alain Delon[8] and Yves Saint Laurent.

The processing of his archive, which contains 120,000 negatives, is in the hands of akg-images[38][39] and is far from over; what has been published in recent years shows, however, that the task here is to snatch the work of a significant figure in the history of photography from oblivion.

In this context, in addition to more recent book publications, there was also an extensive exhibition in the Frankfurt Museum of Modern Art around the turn of the millennium, which was followed by others in Munich's Haus der Kunst and also in Budapest.
