Marcel Duchamp, born in 1887 in Normandy, France, was a prominent figure in 20th-century art, associated with Cubism, Dada, Futurism, and conceptual art. Alongside Pablo Picasso and Henri Matisse, he contributed to revolutionary developments in the plastic arts. Duchamp aimed to use art to serve the mind, rejecting art intended solely to please the eye. Notably, his works "Nude Descending a Staircase" and "Fountain" provoked scandals and raised questions about the nature of art. Duchamp's upbringing in a culturally rich environment, coupled with exposure to art and chess, shaped his artistic inclinations from an early age. Despite an initial focus on classical techniques and subjects, he later embraced Symbolist influences and engaged in play with words and symbols, which continued to inspire his work. His experiences in the military and exposure to typography and printing processes further enriched his artistic endeavors. Duchamp's impact on 20th- and 21st-century art and his pioneering role in the development of conceptual art solidify his legacy as a revolutionary and influential artist.

Marcel François Marie Joseph Lefebvre (29 November 1905 – 25 March 1991) was a French Catholic archbishop who left a significant impact on modern traditionalist Catholicism. He founded the Society of Saint Pius X (SSPX) in 1970 to train seminarians in the traditional manner, and later consecrated four bishops against the pope's prohibition, leading to his excommunication in 1988. Born in Tourcoing, Nord, to devout Catholic parents, Lefebvre was deeply influenced by his father's monarchist views and conservative upbringing. After becoming a priest in 1929, he joined the Holy Ghost Fathers for missionary work and served in various leadership roles, eventually being appointed as the Vicar Apostolic of Dakar, Senegal, in 1947. He was a significant figure in the conservative bloc during the Second Vatican Council and later opposed certain changes within the church associated with the council. Despite facing conflicts with the Holy See, Lefebvre continued to maintain the activities of SSPX, which led to his excommunication. Throughout his life, Lefebvre remained a controversial figure within the Catholic Church due to his staunch traditionalist stance and opposition to certain reforms.
