	title = {The Greek collections of 19th century scientific instruments},
	year = {1999},
	abstract = {At the foundation of the Greek state in 1830, educational institutions like those of Western Europe were created : primary and secondary schools, a military school, a university, a technical school. Later an observatory will also be created. Education and science became then a State affair and the acquisition of scientific instruments too.
