Question: Who initiated the Stockholm Appeal, and was the husband of Irène Joliot-Curie?
Context: Art. 23 1/15 (also referred to as G 2301/15), Art. 23 2/15 (also referred to as G 2302/15) and Art. 23 1/16 are three related cases decided by the Enlarged Board of Appeal of the European Patent Office concerning the removal from office of a member of the Boards of Appeal, who had been previously suspended by the Administrative Council of the European Patent Organisation.  According to Article 23(1) EPC , members of the Boards of Appeal may only be removed from office by the Administrative Council on a proposal from the Enlarged Board of Appeal.  Two cases were successively initiated by the Administrative Council, but the Enlarged Board eventually dismissed both of them.  In the third case initiated by the Administrative Council, the Enlarged Board decided not to propose the removal from office of the member of the Boards of Appeal. Jean Frédéric Joliot-Curie (] ; 19 March 1900 – 14 August 1958), born "Jean Frédéric Joliot", was a French physicist, husband of Irène Joliot-Curie and Nobel laureate. Sound of Stockholm is an annual Swedish festival for contemporary classical music.  The festival is based in Stockholm and was initiated by the composers Henrik Strindberg and Peter Lindroth during the 50-year-anniversary of the chamber music society "Samtida Musik".  The festival is arranged by some of Sweden's most prominent institutions for contemporary music including Samtida Musik, Kroumata, Fylkingen, SEKT and Stockholm Saxophone Quartet.  The festival first took place in 2010, when 1,400 people visited (a high number of people for a contemporary music festival) the 21 concerts and seminars that took place. The Peace Information Center (PIC) was an anti-war organization based in the United States which provided information on peace initiatives in other countries, and promoted the Stockholm appeal.  The organization was in existence from April 3 to October 12, 1950.  Members included O. John Rogge, W. E. B. Du Bois, John T. McManus, Paul Robeson, C. B. Baldwin, Albert E. Kahn, Johannes Steel, Gene Weltfish, Leon Strauss, Elizabeth Moos, Kyrle Elkin, Abbot Simon and Shirley Graham. Ève Denise Curie Labouisse (December 6, 1904 – October 22, 2007) was a French and American writer, journalist and pianist.  Ève Curie was the younger daughter of Marie Skłodowska-Curie and Pierre Curie.  Her sister was Irène Joliot-Curie and her brother-in-law Frédéric Joliot-Curie.  Ève was the only member of her family who did not choose a career as a scientist and did not win a Nobel Prize, although her husband Henry Richardson Labouisse, Jr. did collect the Nobel Peace Prize in 1965 on behalf of UNICEF.  She worked as a journalist and authored her mother's biography "Madame Curie" and a book of war reportage, "Journey Among Warriors".  From the 1960s she committed herself to work for UNICEF, providing help to children and mothers in developing countries. Irène Joliot-Curie (] ; 12 September 1897 – 17 March 1956) was a French scientist, the daughter of Marie Curie and Pierre Curie and the wife of Frédéric Joliot-Curie.  Jointly with her husband, Joliot-Curie was awarded the Nobel Prize for Chemistry in 1935 for their discovery of artificial radioactivity.  This made the Curies the family with the most Nobel laureates to date.  Both children of the Joliot-Curies, Hélène and Pierre, are also esteemed scientists. Hélène Langevin-Joliot (born 19 September 1927) is a French nuclear physicist.  She was educated at the "IN2P3" (English: Institute of Nuclear Physics and Particles ) at Orsay, a laboratory which was set up by her parents Irène Joliot-Curie and Frédéric Joliot-Curie.  She is a member of the French government's advisory committee.  Currently, she is a professor of nuclear physics at the Institute of Nuclear Physics at the University of Paris and a Director of Research at the CNRS.  She is also known for her work in actively encouraging women to pursue careers in scientific fields. Carl Josefsson is a former Swedish Judge at the Svea Court of Appeal in Stockholm, and currently President of the Boards of Appeal of the European Patent Office (EPO), a new position created within the EPO.  He took up his new position on 1 March 2017 for a period of five years.  As President of the Boards of Appeal of the EPO, Josefsson also acts as President of the Enlarged Board of Appeal. The Curie family is a French family with a number of illustrious scientists.  Several members were awarded the Nobel Prize, including physics, chemistry, or the Nobel Peace Prize.  Pierre and Marie Curie, and their daughter Irène Joliot-Curie, are the most prominent members. On March 15, 1950, the World Peace Council approved the Stockholm Appeal, calling for an absolute ban on nuclear weapons.  The appeal was initiated by the French Communist physicist Frédéric Joliot-Curie, gathered petitions allegedly signed by 273,470,566 persons (including the entire adult population of the U.S.S.R.)
