Richard Hodgson joined the ASPR in 1887 to serve as its secretary. In 1889, Fullerton, James and Josiah Royce were Vice-Presidents and Samuel Pierpont Langley served as President. In 1889, a financial crisis forced the ASPR to become a branch of the Society for Psychical Research, and Simon Newcomb and others left. Following the death of Hodgson in 1905 it achieved independence once more.
