The first seismograph was invented by Zhang Heng in 132. The modern seismograph was invented by John Milne, Thomas Gray, and James Alfred Ewing in 1880.
The first seismograph was invented in 132 AD by Chinese astronomer Zhang Heng during the Han dynasty. It was a copper vessel with a pendulum mechanism that could detect and record earthquakes.
John Milne invented the first modern seismograph, but the first ones were invented by Chang Heng around 132 AD.
John Milne invented the seismograph in Tokyo, Japan in the late 19th century. He installed the first modern seismograph at the Imperial University of Tokyo in 1880.
the seismograph was invented in Chicago, 1800.

The first "modern" seismograph was invented by John Milne in 1880. However, Zhang Heng, a Chinese astronomer is also believed to have invented the seismograph; probably the primitive ones.
The first modern seismograph was created by John Milne, a British seismologist, in the late 19th century. Milne's design allowed for the accurate recording of seismic waves and greatly advanced the study of earthquakes.
Europeans began using the seismograph in the 19th century, with the first seismograph being invented in 1880 by John Milne in England. The seismograph revolutionized the study of earthquakes by providing a way to measure and record seismic activity.
Perhaps the earliest seismograph was invented in China A.D. 136 by a m an named Choko.
