Franz Antoine was an Austrian horticulturalist and gardener.
From 1865 he was director of royal gardens to the Austrian/Austro-Hungarian monarchy. He was an authority on the botanical family Bromeliaceae, and was also an avid photographer. His photographs of still lifes, plants and scenes of Vienna were presented at exhibitions in Vienna (1864, 1873) and Paris (1867). His father, Franz Antoine the Elder (1768-1834), was also a gardener to Austrian royalty, with a gardener's residence – the younger Franz' birthplace – in the Paradeisgartl garden, now part of the Volksgarten, Vienna.
