The beaker was invented around the 16th century. It is believed to have been developed in Europe, likely by alchemists or chemists during the Renaissance period. The exact date and inventor of the beaker are unknown.

The first school binder was invented in the 1850s by a Swedish inventor named Rudolf Granberg. Granberg developed a type of loose-leaf notebook that allowed pages to be easily added or removed, similar to modern binders.
The first school desk is believed to have been invented in the 18th century, specifically in the early 1800s in the United States. It was designed to provide a more organized and structured learning environment for students in classrooms.
School bells were invented in the early 19th century, around the 1820s. They were used to signal the beginning and end of classes, breaks, and other activities in schools. Initially, they were operated manually before being automated with the advancement of technology.
The first summer school is often attributed to Harvard University, which established its Summer School in 1871. This was designed to provide additional educational opportunities for students during the summer months.

According to what I've read and researched the beaker has been around sinse the first century. So there is no real founder of the beaker!

The eureka beaker is a beaker to find out the density of irregular shaped objects. Archimedes invented it when he stepped into his bath and saw that the water level rose. He shouted "Eureka!" which means "i have found it!".
It was invented in 1903 by a french chemist when he dropped a glass beaker coated in viscous collodion and it shattered, but didn't come apart because of the coating.

A glass beaker is completely filled with 456 c.c. of a liquid when both the glass beaker and the liquid are at a temperature of 33.3oC. If the glass beaker and the liquid are cooled to 5oC. what additional volume of liquid (in c.c.) can be put into the beaker?Volumetric coefficient of expansion of liquid is 0.000109K-1 and the coefficient of linear expansion for glass is 3.2X10-6K-1
The laboratory beaker is characterized by having a 'beak' at the rim, which aids pouring. It was invented by J J Griffin, possibly in the 1850's. His firm eventually was the foundation of Griffin & George, major suppliers of lab chemicals and equipment.
You must obtain and subtract the mass of the beaker.
Inform their teacher and then throw the beaker in the broken glass
