Yves Klein followed his parents as they moved between their various residences. The Kleins lived in Paris but spent every summer at Cagnes-sur-Mer, where Marie Raymond’s sister Rose Raymond lived. Yves literally adored his aunt, who constantly doted on, assisted, and supported him. From the summer of 1939 until 1943, the Kleins lived in Cagnes-sur-Mer, situated in the non-occupied zone.
