Hello Santosh,

In 1801, Marie François Xavier Bichar discovered the word called as "Tissue". He was a Physiologist and Anatomist. He observed that group of cells formed as tissues and rather than entities in themselves.

He proposed that tissue is a human anatomy's central element. He also considered organs comprises of tissues.

The study of tissues is called as Histology and that's why he was called as "Father of Histology".

I hope this information was helpful to you.

All The Best!!
