Mary Ward died #OTD in 1869.

Ward was a keen amateur astronomer and she built the Leviathan of Parsonstown, a reflecting telescope with a six-foot mirror which remained the world's largest until 1917. Ward was a frequent visitor to Birr Castle, producing sketches of each stage of the process. Along with photographs made by Parson's wife Mary Rosse, Ward's sketches were used to aid in the restoration of the telescope. via nostr:npub1kvnpp3m60derhwpqwc09zhk3ehk48tr6agc6dk9z2vggu9sga28qpxhm73
