Who among the following had founded the Theosophical Society in the United States of America ?

The Theosophical Society was founded in New York City, United States, in 1875 [c1][t1]. The primary founders were Madame Helena Petrovna Blavatsky, a Russian noblewoman and occultist, and Colonel Henry Steel Olcott, an American veteran [c1][c2][t2]. They were later joined by William Quan Judge [t1][t4]. The society was inspired by Indian thought, particularly the philosophy of the Upanishads, Vedanta, and the concepts of reincarnation and karma [c1]. In 1879, the founders moved to India and eventually established their international headquarters at Adyar, near Madras, in 1882 [c1][c3]. While Swami Dayanand Saraswati's Arya Samaj briefly united with the society between 1878 and 1882, he was not a founder [t8][t9]. Madame Cama and Lala Hardayal were associated with the Indian independence movement and the Ghadar Party, respectively, rather than the founding of this spiritual organization.
