Context: Welland Lathrop (1905–1981) was a dancer, teacher, painter, and choreographer and a leader of the west coast modern and avant-garde dance movement.  Born in upstate New York, he initially trained in costume and scenic design at the Eastman Theater in Rochester, New York.  In 1928 he moved to San Francisco to continue his design education under Rudolph Schaeffer.  While in San Francisco, he began studying dance with Ann Mundstock of the Laban School.  Later training included the Cornish School in Seattle, Washington (1930–1934) and the Neighborhood Playhouse School of the Theater (1938–1941) where he was an assistant in dance composition to Louis Horst.

The pond loach, dojo loach (ドジョウ , dojō ) , or oriental/Japanese weather loach ("Misgurnus anguillicaudatus"), is a freshwater fish in the loach family Cobitidae.  They are native to East Asia but are also popular as an aquarium fish and introduced elsewhere in Asia and to Europe, North America and Australia.  The alternate name weather loach is shared with several other Cobitidae, including the other members of the genus "Misgurnus" and the spotted weather loach ("Cobitis taenia", commonly known as spined loach).  This term comes from their ability to detect changes in barometric pressure and react with frantic swimming or standing on end.  This is because before a storm the barometric pressure changes, and this is known to make these fish more active.  The pond loach also comes in a variety of colors, such as pink, orange, albino and gray. Robert (Rob) Stuart Howell is a British costume and set designer.

Candide is an operetta with music composed by Leonard Bernstein, based on the 1759 novella of the same name by Voltaire.  The operetta was first performed in 1956 with a libretto by Lillian Hellman; but since 1974 it has been generally performed with a book by Hugh Wheeler which is more faithful to Voltaire's novel.  The primary lyricist was the poet Richard Wilbur.  Other contributors to the text were John Latouche, Dorothy Parker, Lillian Hellman, Stephen Sondheim, John Mauceri, John Wells, and Bernstein himself.
