He was an exceptional student, and graduated from the <em>Paris Conservatoire<\/em> with first prizes in viola, harmony, counterpoint and orchestra conducting. Armed with these diplomas, he initially pursued a career as a violist, before devoting himself to conducting, and he was encouraged in particular in this path by the composer Vincent d\u2019Indy. On 14 March 1924, he had the honour of conducting the premiere of Arthur Honegger&#8217;s <em>King David<\/em> at the prestigious Salle Gaveau in Paris.

Far from merely performing a series of concert, this ensemble was a true musical laboratory where the most innovative voices of the time could express themselves. This series of concerts, held in various Parisian venues, quickly became a must on the music scene.<\/p>\n\n\n\n<p>Siohan introduced daring works, often performed for the first time, such as Olivier Messiaen&#8217;s <em>L&#8217;Ascension<\/em> (1934), as well as scores by Darius Milhaud, Jacques Ibert, Arthur Honegger and Georges Auric.<\/p>\n\n\n\n<p>These concerts were ahead of their time, and could be seen as a forerunner of <a href=\"https:\/\/www.ina.fr\/ina-eclaire-actu\/video\/i15054209\/pierre-boulez-et-les-concerts-du-domaine-musical\"><em><u>Domaine Musical<\/u><\/em>,<\/a> the concert society founded in 1954 in Paris by Pierre Boulez.<\/p>\n\n\n\n<p>This aspect of Siohan&#8217;s career is particularly well documented in the collection being sold at Vichy Ench\u00e8res. It includes 34 posters relating to the <em>Siohan Concerts<\/em>, as well as some 40 programmes, handwritten accounts and various documents on the subject. In particular, they cover the 1934 premiere of Messiaen&#8217;s <em>L&#8217;Ascension<\/em>, a work laying the foundation for French modernity. Several documents also allow us to take an intimate peek into this artistic circle, including a card addressed to Corrie Siohan [1], the conductor&#8217;s wife and collaborator, which bears the signatures of Honegger, Charles Munch and Siohan himself. This card reminds us that, behind the artistic innovation, bonds of friendship were forged.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p style=\"font-size:15px\"><a id=\"_ftn1\" href=\"#_ftnref1\"><sup>[1]<\/sup><\/a> A card on which is typed &#8220;Madame SIOHAN&#8221; on which several people have written and signed compliments.

It contains several hundred original documents, manuscripts and typescripts by Robert Siohan, recounting what he called &#8220;Three years of distress&#8221;. After the Liberation in 1945, Siohan took a stand against Jacques Rouch\u00e9, the general administrator of the <em>Th\u00e9\u00e2tres Lyriques Nationaux<\/em>, who had collaborated with the authorities during the Occupation of France.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>Having worked at the <em>Th\u00e9\u00e2tre Lyrique de l&#8217;Op\u00e9ra (Paris)<\/em> since 1932 as Chorus Director, I found myself actively involved in the Rouch\u00e9 Affair after the Liberation, having taken a resolute stand against him. [\u2026] There is indeed no doubt that at the Opera, as in the country more generally, two camps clashed, with those who sought to minimize, excuse and even justify collaboration, reacting violently against those who condemned it.<\/p>\n\n\n\n<p style=\"font-size:15px\">Preamble to a report drawn up by Robert Siohan in September 1945<\/p>\n<\/blockquote>\n<\/div>\n<\/div>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-21 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/03-jacques-rouche.png\"><img decoding=\"async\" data-id=\"29613\" src=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/03-jacques-rouche.png\" alt=\"Jacques Rouch\u00e9 - Administrateur g\u00e9n\u00e9ral des Th\u00e9\u00e2tres lyriques nationaux\" class=\"wp-image-29613\"\/><\/a><figcaption class=\"wp-element-caption\">Jacques Rouch\u00e9, General Administrator of the Th\u00e9\u00e2tres lyriques nationaux<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/04-opera-garnier-sous-occupation.png\"><img decoding=\"async\" data-id=\"29615\" src=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/04-opera-garnier-sous-occupation.png\" alt=\"L'Op\u00e9ra Garnier \u00e0 Paris, sous l'occupation\" class=\"wp-image-29615\"\/><\/a><figcaption class=\"wp-element-caption\">The Op\u00e9ra Garnier in Paris during the Occupation.<\/figcaption><\/figure>\n<\/figure>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>This brave stance, on the side of those who sought to purge public institutions from collaborators, cost him dearly. He quickly encountered the hostility of many Opera musicians, who refused to accept him as conductor. Obstacles were then put in his way. A petition dated 3 October 1945 from the Opera orchestra, to overturn his appointment, was signed by 64 musicians.<\/p>\n\n\n\n<p>In the face of this hostility, a prestigious front of support formed, as evidenced by the numerous letters included in the file, and signed by Georges Auric, Olivier Messiaen, Henri Dutilleux, Arthur Honegger, Jacques Ibert, Louis Durey and Jacques Copeau. For instance, Messiaen wrote to him in July 1947 to reiterate his esteem and friendship. These famous artists defended the integrity and talent of Robert Siohan, who had been unjustly marginalized.<\/p>\n\n\n\n<p>This affair revealed the extent of the divisions in society at the time, in all its spheres. The Siohan affair embodied these tensions and also revealed the strength of character of an artist who, at the cost of his career, remained true to his convictions.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/vichy-encheres.com\/09-lettres-soutien-personnalites-robert-siohan\/\"><img decoding=\"async\" src=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/09-lettres-soutien-personnalites-robert-siohan.png\" alt=\"Lettres de personnalit\u00e9s en soutien \u00e0 Robert Siohan.\" class=\"wp-image-29627\"\/><\/a><figcaption class=\"wp-element-caption\">Letters from prominent figures in support of Robert Siohan.<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h1 class=\"wp-block-heading\">The teacher and the critic<\/h1>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-22 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/11-ensemble-archives-articles-robert-siohan-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" data-id=\"29718\" src=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/11-ensemble-archives-articles-robert-siohan-1024x576.jpg\" alt=\"Ensemble d\u2019archives sur les articles de Robert Siohan\" class=\"wp-image-29718\" srcset=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/11-ensemble-archives-articles-robert-siohan-1024x576.jpg 1024w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/11-ensemble-archives-articles-robert-siohan-300x169.jpg 300w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/11-ensemble-archives-articles-robert-siohan-768x432.jpg 768w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/11-ensemble-archives-articles-robert-siohan-1536x864.jpg 1536w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/11-ensemble-archives-articles-robert-siohan-2048x1152.jpg 2048w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/11-ensemble-archives-articles-robert-siohan-1568x882.jpg 1568w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/11-ensemble-archives-articles-robert-siohan-100x56.jpg 100w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n<figcaption class=\"blocks-gallery-caption wp-element-caption\">Archives of articles by Robert Siohan<\/figcaption><\/figure>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns are-vertically-aligned-top is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-top is-layout-flow wp-block-column-is-layout-flow\">\n<p>Whilst the affair marked a turning point in his career, Siohan was able to bounce back. In 1945, he was appointed to a sight-reading class at the <em>Conservatoire<\/em>, where he taught until 1962. That same year, he was appointed Inspector General of Music Education, alongside Andr\u00e9 Malraux, then Minister of Cultural Affairs. However, it was above all as a music critic that Siohan reinvented himself. He published a significant number of articles for <em>Le Monde<\/em>, contributing in the process to the expansion of the newspaper&#8217;s music section. Most of his articles \u2013 nearly 500, written between 1954 and 1971 \u2013 are preserved in the collection of documents now brought to light.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-top is-layout-flow wp-block-column-is-layout-flow\">\n<p>These articles cover the avant-garde scene of the 1950s and 1960s, from electronic music to the <em>Domaine Musical<\/em> concerts, and provide a testament to the way in which new music was received in France at that time. This collection also serves as a reminder that Siohan was not only a key figure in contemporary music, but also one of its greatest proponents.<\/p>\n\n\n\n<p>Robert Siohan was awarded the rank of Chevalier of the Legion of Honour in 1936, that of Officer of Arts and Letters in 1957, and then promoted to Officer of the Legion of Honour in 1961.

In particular it contains the complete manuscript of his book <em>Stravinsky<\/em>, published in 1959, accompanied by hundreds of preparatory notes. The work, published in the <em>Solf\u00e8ges du Seuil<\/em> collection, remains a reference today. The books also contain handwritten congratulations from Nadia Boulanger, Alfred Cortot and Vladimir Jank\u00e9l\u00e9vitch, which attests to the quality of his work. Alongside <em>Stravinsky<\/em>, the collection includes files on <em>Histoire du public musical<\/em> (1967) and <em>La musique \u00e9trang\u00e8re au XXe si\u00e8cle<\/em> (1984).<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>Through these works, Siohan expressed his desire to broaden our perspective and to position contemporary music within a long and diverse history. These corrected proofs and original editions offer a sensitive and more intimate insight into his inner workings, as do the 70 handwritten notebooks written between 1936 and 1980. These provide analyses of works, aesthetic reflections, and even concert notes, which combine to form a day-by-day chronicle of half a century of musical reflection.<\/p>\n<\/div>\n<\/div>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-24 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/13-traductions-livre-stravinsky-lettres-felicitations-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"2560\" height=\"1982\" data-id=\"29669\" src=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/13-traductions-livre-stravinsky-lettres-felicitations-scaled.jpg\" alt=\"L'ouvrage de Stravinsky de Robert Siohan a \u00e9t\u00e9 traduit dans plusieurs langues et a re\u00e7u de nombreuses f\u00e9licitations.\" class=\"wp-image-29669\" srcset=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/13-traductions-livre-stravinsky-lettres-felicitations-scaled.jpg 2560w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/13-traductions-livre-stravinsky-lettres-felicitations-300x232.jpg 300w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/13-traductions-livre-stravinsky-lettres-felicitations-1024x793.jpg 1024w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/13-traductions-livre-stravinsky-lettres-felicitations-768x595.jpg 768w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/13-traductions-livre-stravinsky-lettres-felicitations-1536x1189.jpg 1536w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/13-traductions-livre-stravinsky-lettres-felicitations-2048x1586.jpg 2048w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/13-traductions-livre-stravinsky-lettres-felicitations-1568x1214.jpg 1568w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/13-traductions-livre-stravinsky-lettres-felicitations-100x77.jpg 100w\" sizes=\"auto, (max-width: 2560px) 100vw, 2560px\" \/><\/a><figcaption class=\"wp-element-caption\">Robert Siohan&#8217;s Stravinsky has been translated into several languages and has received many accolades.<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/14-histoire-du-public-musical-notes-travail-robert-siohan-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1920\" height=\"2560\" data-id=\"29722\" src=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/14-histoire-du-public-musical-notes-travail-robert-siohan-scaled.jpg\" alt=\"L'histoire du Public Musical et les notes de travail de Robert Siohan\" class=\"wp-image-29722\" srcset=\"https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/14-histoire-du-public-musical-notes-travail-robert-siohan-scaled.jpg 1920w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/14-histoire-du-public-musical-notes-travail-robert-siohan-225x300.jpg 225w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/14-histoire-du-public-musical-notes-travail-robert-siohan-768x1024.jpg 768w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/14-histoire-du-public-musical-notes-travail-robert-siohan-1152x1536.jpg 1152w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/14-histoire-du-public-musical-notes-travail-robert-siohan-1536x2048.jpg 1536w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/14-histoire-du-public-musical-notes-travail-robert-siohan-1568x2091.jpg 1568w, https:\/\/vichy-encheres.com\/wp-content\/uploads\/2025\/09\/14-histoire-du-public-musical-notes-travail-robert-siohan-75x100.jpg 75w\" sizes=\"auto, (max-width: 1920px) 100vw, 1920px\" \/><\/a><figcaption class=\"wp-element-caption\">The history of Public Musical and Robert Siohan&#8217;s working notes<\/figcaption><\/figure>\n<\/figure>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<blockquote class=\"wp-block-quote is-style-large is-layout-flow wp-block-quote-is-layout-flow\">\n<p><em>From virtuoso violist to founder of the Siohan Concerts, from witness of wartime collaboration to perceptive critic for Le Monde, from author of Stravinsky to proponent of new music, Robert Siohan was a multifaceted individual who saw in modernity not a break from the past, but a continuity.
