Dr Edmund Locard is the father of modern forensics. It was the advancements by Locard that has shaped the way forensics work today.

Locard studied medicine and law in Lyon, France and eventually joined the French police in 1910. In the police force he requested his superiors give him two quiet rooms and two assistants, which he was given. This became the worlds first ever forensic laboratory.

Locard is also known as the "Sherlock Holmes of France." He famously said "Every contact leaves a trace" (meaning every criminal leaves a clue behind no matter how careful they are). The same principle is applied today in modern forensics.

However there have been many other fathers and founding-evidences of forensics:

700 BC - Archaeologists discovered fingerprints in Ancient Babylon dating back to 700BC imprinted in clay tablets. They were used for criminal records and business transaction records.
287 BC - Archimedes in Ancient Greece proves a royal crown was fake and not made of gold using density and buoyancy.
250 BC - Erasistratus in Ancient Greece discovers that when people lie, their pulse gets faster. This was used as the first lie detection method.
Around 1235 AD - Sung Tzu (no relation to Sun Tzu), a Judicial Intendant (judge) during China's Sung Dynasty uses the study of bugs to solve a murder. A murder was committed using a sickle. Everybody in the village of the murder was ordered to stand in a line outside the village in the hot sun, surrounded by Chinese soldiers, with their sickles on the ground in front of them. The plan was to either get someone to crack in the heat and confess, or test a theory he had about bugs and dried blood. Eventually, flies gathered on one particular sickle. When the sickle was broken apart, dry blood was found trapped inside after seeping into the handle. The owner of the sickle was charged with murder.
1248 AD - A book is published in China, "His Duan Yu", meaning "The Washing Away of Wrongs". It contained detailed forensic observations on how to tell if someone drowned accidently or on purpose and how to distinguish between deaths by drowning and deaths by strangulation.
1302 - Bartolomeo da Varignana performs the first official forensic autopsy on a murder victim.

1775 - Advancements in investigating poison-related deaths thanks to Karl Whilhelm Scheele. He discovered that arsenious oxide can be changed into arsenious acid, which was used in forensic detection of arsenic poison.
1786 - John Toms, from England, is convicted of murder. The gunpowder in the pistol he had hidden in his pocket leaked and created a perfect outline of the pistol on a piece of paper in the same pocket. He shot his victim and threw the gun away nearby. He was caught by matching the shape of the gun to the outline on the paper found in his pocket. The first recorded use of physical matching forensics.
