Early cave artists and pot makers “sign” their works with a paint or impressed finger or thumbprint. 

# data[].attributes.body
This time in history is very important because it shows one of the first records of fingerprinting. This will eventually turn into the greatest data base we use today to collect fingerprint profiles.

Erasistratus (c. 304–250 b.c.) and Herophilus (c. 335–280 b.c.) perform the first autopsies in Alexandria.

# data[].attributes.body
This era is important to the forensic science community because it is the first times they preformed an autopsy. This technique will start to develop in the world of medicine and will be used to give people closure of a unknown illness that might of taken their loved one

King Richard Plantagenet (1157–1199) officially creates the position of coroner.

# data[].attributes.body
With this new position in hand this will create a way to be able diagnose diseases and can help find a cure for dangerous ones. With a professional doing this job it will start the legacy of a forensic pathologist in future medicine.

Medical schools are established in Padua and Bologna.

# data[].attributes.body
This will create opportunities for many people and educate generations of future doctors in the world. This will provide many new discoveries in medicine and lead to more understanding in forensic science.

Zacharias Janssen (c. 1580–c. 1638) designs the first crude microscope with the help of his father, Hans.

# data[].attributes.body
This is very important because it will tell us the microscopic world within our bodies. In the forensic science community this is important because we will learn more about how diseases replicate and spread, also showing evidence that is not visible to the naked eye.

Francois Demelle publishes the first treatise on document examination in France.

# data[].attributes.body
This writing was the start of many published books of medicine to come. These writings will serve as references to future illnesses and will even be changed due to the evolution of science.

1685: Marcello Malpighi first recognizes fingerprint patterns and uses the terms loops and whorls

# data[].attributes.body
I chose to input this event because it is the first glance of how we describe different finger prints. This will then be used to catch many criminals that commit horrendous acts of violence.

Paul Revere recognizes dentures he had made for his friend Dr. Joseph Warren and thus identifies the doctor’s body in a mass grave at Bunker Hill.

# data[].attributes.body
This is a major forensic advancement in history because it showed us we can use certain things in peoples bodies to identify them. This will play a huge role in forensic science and autopsies when there are only skeletal remains.

Johann Metzger develops a method for isolating arsenic

# data[].attributes.body
This was very important in the forensic science community because it will save many people of arsenic poisoning. Not only this, it will show how much arsenic is in everyday items and will save many people from long term affects.

The first use of document examination in a criminal investigation involves the analysis of ink dye on a document known as Konigin Hanschritt in Germany

# data[].attributes.body
This will be use in many instances to catch people that tried to commit fraud or even write suicide letters to cover up their own murder. This development was used many times to catch people in the wrong back then and even today.

 Mathieu Joseph Bonaventure Orfila (1787–1853) publishes Traité des poisons (Treatise on Poison), the first toxicology textbook. 

# data[].attributes.body
This is very important because it gave many references for the forensic science community to look back on. This will be the foundation to many more toxicology reports and could lead to many more discoveries.

# data[].attributes.attachment_caption
Johannes Purkinje (1787–1869) devises the first crude fingerprint classification system.

# data[].attributes.body
I chose to include this event because it will create the foundation for the amazing data base we have today called IAFIS. This data base is still used today to collected thousands of fingerprint that could potentially bring justice.

Masaeo Takayama develops a microcrystalline test for blood hemoglobin.

# data[].attributes.body
I chose to put this into my collection because it was very important to the forensic science community. It created many ways to see blood that wasn’t visible to the naked eye as criminals tried to cover up their tracks.

Victor Balthazard (1872–1950) publishes his belief that each fired bullet carries unique marks.

# data[].attributes.body
This will make it easier to distinguish which weapon was used as a potential murder weapon. It is very important in the forensic science community because it showed how minor details can potentially lead to someones killer going behind bars.

Oswald Avery (1877–1955), Colin MacLeod (1909–1972), and Maclyn McCarty (1911–2005) discover that DNA carries genetic information. 

# data[].attributes.body
DNA is passed down from your parents to you. This could lead to major breakthroughs in a case. This certain tool is called genetic fingerprint profiling.

Mitochondrial DNA is first admitted into a U.S. court in Tennessee v. Ware. 

# data[].attributes.body
This is important because the high sensitivity of mtDNA allows forensic scientists to obtain information old items of evidence and can reopen cold cases.

# data[].attributes.attachment_caption
The National DNA Index System (NDIS) becomes operational.

# data[].attributes.body
This database had more than 14 million offender profiles and more than 4 million of those have been convicted of a crime. This data is putting dangerous criminals behind bars today, and will keep our community safe.

Footwear detection system: Britain's Forensic Science Service develops online footwear coding and detection system. This helps police to identify footwear marks

# data[].attributes.body
This is important because investigators are finding faster ways to identify and pin point a criminal. It is important because they can use this data base to track when and where a certain shoe was purchased.

# data[].attributes.attachment_caption
A way for scientists to visualize fingerprints even after the print has been removed is developed, relating to how fingerprints can corrode metal surfaces.

# data[].attributes.body
This is a major breakthrough in the forensic science community because they can find fingerprints even after the criminal has tried to clean them away. They can use this to trace the criminals steps and lead to justice in the community.

 This system can automatically match dental x-rays in a database, and makes a positive match in less than 4 seconds. 

# data[].attributes.body
With families struggling with cold cases today, they can use this fast database to find a match in seconds to lead to faster closer. This advancement will also aid the investigators when they are trying to pin point who the person is immediately.
