The fact that light had speed was well known as far back as the ancient Greeks. However it would not be until modern times that equipment was sensitive enough to deduce with a margin or error, something close to the accepted value.
In 1983 at the Conférence Générale des Poids et Mesures an exact value for the speed of light in a vacuum was set at 299,792.458 m/s [See Link]

Who discovered that electromagnetic waves can travel through empty space at the speed of light?
James Clerk Maxwell.
Who was the scientist who discovered that heavy and light body of the same substance fall at the same speed?
Galileo I think.
How did Albert Einstein determine the speed of light?
Albert Einstein did not determine the speed of light, rather that the speed of light was the maximum speed possible in the universe. The speed of light was discovered in the late 1600's by Danish astronomer Ole Roemer, using Jupiter and its moon Io. It was later used in Maxwell's equations of electromagnetism, and then later used by Albert Einstein in his theory of special relativity.
When velocity of light was discovered?
In 1728, James Bradley deduced that starlight falling on the Earth should appear to come from a slight angle, which could be calculated by comparing the speed of the Earth in its orbit to the speed of light. This "aberration of light", as it is called, was observed to be about 1/200 of a degree. Bradley calculated the speed of light as about 298,000 km/s (186,000 mi/s).
What is faster Speed of Light or Speed of Eyesight?
The speed of light.
What is Michelson famous for?
he discovered the speed of light
Why is light speed the ultimate?
This is because nothing else in the entire discovered universe moves as fast as the speed of light!
Who discovered the equation energy times speed of light squared?
Einstein
Who was the first to find the speed of light?
it was MAxwell the dude who discovered electromagnetic waves
What did Olaus Roemer invent?
Olaus Roemer discovered the speed light in 1676.
What can be discovered if something is found which has greater speed than light?
probably all kinds of technology
Is sound the fastest speed possible?
No!...Speed of light is the fastest speed possible, but now a new particle called lepton is more faster than light...rather it is has the fastest speed discovered till now.It travels in the same wave as light travels i.e tranverse waves.
Who discovered that electromagnetic waves can travel through empty space at the speed of light?
James Clerk Maxwell.
Who was the scientist who discovered that heavy and light body of the same substance fall at the same speed?
Galileo I think.
Who discovered that the electric current flows at the speed of light?
A german physicist named Gustav Robert Kirchhoff was the first scientist to show that eletric current flows at the speed of light through a conductor.
When was speed discovered?
The second species in any environment.It was either a predator and wanted to move faster than the first to catch and eat it, or it was the prey and wanted to get away! So several millions of years before the first humanoid.
