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]

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.
Which recently discovered particle has velocity more than that of photon in light?
The neutrino was recently discovered to have a velocity greater than that of light in a vacuum. This discovery was made in experiments such as OPERA where neutrinos were observed traveling faster than the speed of light, although those results were later retracted.
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 does special relativity say about the speed of light?
The speed of light is constant.
Who was the scientist who discovered that heavy and light body of the same substance fall at the same speed?
Galileo Galilei, an Italian scientist, is credited with the discovery that heavy and light bodies of the same substance fall at the same speed in a vacuum. He conducted experiments to demonstrate this principle of free fall.
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
What did Olaus Roemer invent?
Olaus Roemer discovered the speed light in 1676.
Who was the first to find the speed of light?
it was MAxwell the dude who discovered electromagnetic waves
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.
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.
When Michelson and Morley measured the speed of light in various directiion they discovered that?
... its speed is the same in any direction, even if you're movingin that direction or in the direction opposite to it.
Is it true albert invent speed of light?
No, the speed of light was not invented - it's a natural phenomenon. Albert Einstein discovered the equation E=mc2. This tells us that if an object was to randomly turn into energy, the amount of energy would be equal to the objects mass multiplied by the speed of light twice.
What did Olaus Roemer discover about light?
Olaus Roemer discovered the finite speed of light in the late 17th century. He observed that the time it took for light to travel from Jupiter to Earth varied as the distance between the two planets changed, leading him to calculate a rough estimate of the speed of light. This discovery laid the foundation for later, more precise measurements of the speed of light.
Who discovered that the electric current flows at the speed of light?
The discovery that electric current flows at the speed of light is attributed to a Scottish physicist named James Clerk Maxwell. In his equations known as Maxwell's equations, he determined that the speed of electromagnetic waves, which includes light and electricity, is constant and equal to the speed of light.
