Discovery circumstances

Credit for the discovery of 886 Washingtonia has been given to George Peters of the US Naval Observatory, who was the first to report it. The object was, however, observed four days earlier by Margaret Harwood, who was advised not to report it as a new discovery because "it was inappropriate that a woman should be thrust into the limelight with such a claim".[2] The first woman to be credited with the discovery of a minor planet was Pelageya Fedorovna Shajn, eleven years later.^{[citation needed]}
