Пьер Кюри родился 15 мая 1859 г. в Париже в семье врача. Эжен Кюри, отец Пьера, во время революции 1848 г., в дни Парижской Коммуны был на боевом посту, оказывая помощь раненым революционерам и коммунарам. Человек высокого гражданского долга и мужества, он привил эти качества своим сыновьям Жаку и Пьеру. Мальчики — шестнадцатилетний Жак и двенадцатилетний Пьер помогали отцу в дни баррикадных боев Коммуны.<span>
