Michael Wardian was born on 1974-04-12.

It was invented by Dr. Nathaniel Bagshaw Ward who created a "Wardian Case" to hold his ferns and prevent them from dying from London's air pollution.

Because a terrarium is a noun, you can't have an opposite of it (antonym = opposite). If you're looking for a synonym (another word with the same/similar meaning) then you can use "Wardian Case".
