San Francisco Microscopical Society.

The San Francisco Microscopical Society was formed in 1870, when the California Academy of Sciences declined a proposal by two members, Hiram G. Bloomer and Henry G. Hanks, to form a section devoted to the use of microscopes in scientific studies. Within a year the Society was nearly inactive. However, interest revived the Society in 1872, with a new organizational structure and fees to support equipment and other expenses. The Society disbanded in early 1906.

Organizational History

The San Francisco Microscopical Society was formed in 1870, when the California Academy of Sciences declined a proposal by two members, Hiram G. Bloomer and Henry G. Hanks, to form a section devoted to the use of microscopes in scientific studies. Within a year the Society was nearly inactive. However, interest revived the Society in 1872, with a new organizational structure and fees to support equipment and other expenses.

Members met monthly to discuss their research and to promote scientific study. Papers on subjects such as geology, biology, and botany were presented for discussion and visiting scientists were brought in to share ideas and demonstrate new scientific equipment. The Society also elected corresponding members from other states and countries. Through exhibits, receptions, a journal, and proceedings published in local newspapers, the Society publicized their research efforts.

The Society disbanded just before the 1906 San Francisco earthquake and fire. Its property and library were donated to the University of California at Berkeley. The Society was re-formed in 1946 by George H. Needham, and continues to date.
