(1882-1940) English sculptor, engraver, and writer. He designed the typefaces Perpetua 1925 and Gill Sans (without serifs) 1927, and created monumental stone sculptures with clean, simplified outlines, such as Prospero and Ariel 1929–31 (on Broadcasting House, London).
He studied lettering at the Central School of Art in London under Edward Johnston (1872–1944), and began his career carving inscriptions for tombstones. Gill was a leader in the revival of interest in the craft of lettering and book design. His views on art combine Catholicism, socialism, and the Arts and Crafts tradition.

(1843-1914) Scottish astronomer who pioneered the use of photography to catalog stars. He also made much use of a heliometer, determining the solar parallax and measuring the distances of 20 of the brighter and nearer southern stars.
Gill was born in Aberdeen and studied there at Marischal College; he then went to Switzerland to learn clockmaking. In 1872, he became director of Lord Lindsay's private observatory at Dun Echt, near Aberdeen. He was astronomer at the observatory at the Cape of Good Hope, South Africa, 1879–1906.
With Lord Lindsay, Gill went on an expedition to Mauritius 1872–78 in order to measure the distance of the Sun and other related constants, particularly during the 1874 transit of Venus.
In 1882 Gill realized it should be possible to chart and measure star positions by photography. He initiated a vast project, with the help of other observatories, to produce the Cape Durchmusterung, which gives the positions and brightness of more than 450,000 southern stars. Gill also served on the council for the International Astrographic Chart and Catalog, which was to give precise positions for all stars to the 11th magnitude. It was not completed until 1961, although all the photographs had been taken by 1900.

Any of the radiating leaflike spore-producing structures on the underside of the cap of a mushroom or similar fungus; SYN. lamella.

In biology, the main respiratory organ of most fishes and immature amphibians, and of many aquatic invertebrates. In all types, water passes over the gills, and oxygen diffuses across the gill membranes into the circulatory system, while carbon dioxide passes from the system out into the water.
In aquatic insects, these gases diffuse into and out of air-filled canals called tracheae.
Respiratory organ of aquatic animals that breathe oxygen dissolved in water; SYN. branchia.
