Jeffrey Lionel Dahmer (May 21, 1960 – November 28, 1994), also known as the Milwaukee Cannibal or the Milwaukee Monster, was an American serial killer and sex offender who killed and dismembered seventeen males between 1978 and 1991.

Many of his later murders involved necrophilia, cannibalism, and the permanent preservation of body parts—typically all or part of the skeleton.

Although he was diagnosed with borderline personality disorder (BPD), schizotypal personality disorder (StPD), and a psychotic disorder, Dahmer was found to be legally sane at his trial.

Jeffrey Dahmer was born on May 21, 1960, in Milwaukee, Wisconsin, the first of two sons to Lionel Herbert Dahmer, a Marquette University chemistry student and later a research chemist, and Joyce Annette Dahmer, a teletype machine instructor.

Lionel was of German and Welsh ancestry, and Joyce was of Norwegian and Irish ancestry.

Some sources report Dahmer was deprived of attention as an infant.

Other sources, however, suggest that Dahmer was generally doted upon as an infant and toddler by both parents, although his mother was known to be tense, greedy for both attention and pity, and argumentative with her husband and their neighbors.

As Dahmer entered first grade, Lionel's studies kept him away from home much of the time.

When he was home, his wife—a hypochondriac who suffered from depression—demanded constant attention and spent an increasing amount of time in bed.

On one occasion, she attempted suicide using Equanil.

Neither parent devoted much time to their son, who later recollected that, from an early age, he felt "unsure of the solidity of the family", recalling extreme tension and numerous arguments between his parents during his early years.

Dahmer had been an "energetic and happy child" but became notably subdued after undergoing double hernia surgery shortly before his fourth birthday.

At elementary school, Dahmer was regarded as quiet and timid.

One teacher recollected she detected early signs of abandonment due to his father's absence and mother's illnesses, the symptoms of which increased when she became pregnant with her second child.

In elementary school, Dahmer had a small number of friends.

In October 1966, the family moved to Doylestown, Ohio.

When Joyce gave birth in December, Dahmer was allowed to choose the name of his new baby brother; he chose the name David.

The same year, Lionel earned his degree and started work as an analytical chemist in nearby Akron, Ohio.

From an early age, Dahmer manifested an interest in dead animals.

His fascination with dead animals may have begun when, at the age of four, he saw his father removing animal bones from beneath the family home.

According to Lionel, Dahmer was "oddly thrilled" by the sound the bones made, and became preoccupied with animal bones, which he initially called his "fiddlesticks".

He occasionally searched beneath and around the family home for additional bones, and explored the bodies of live animals to discover where their bones were located.

In May 1968, the family moved to Bath Township, Summit County, Ohio.

This address was their third in two years, and the Dahmers' sixth address since marriage.

The home stood in one and a half acres of woodland, with a small hut a short walk from the house where Dahmer began collecting large insects and the skeletons of small animals, such as chipmunks and squirrels.

Some of these remains were preserved in jars of formaldehyde and stored within the hut.

Two years later, during a chicken dinner, Dahmer asked Lionel what would happen if the chicken bones were placed in bleach.

Lionel, pleased by what he believed to be his son's scientific curiosity, demonstrated how to safely bleach and preserve animal bones.

Dahmer incorporated these preserving techniques into his bone collecting.

He also began collecting dead animals—including roadkill —which he would dissect and bury beside the hut, with the skulls occasionally placed atop makeshift crosses.

According to one friend, Dahmer explained that he was curious as to how animals "fit together".

In one instance in 1975, Dahmer decapitated the carcass of a dog before nailing the body to a tree and impaling the skull upon a stick in the woodland behind his house.

As a "prank", he later invited a friend to view the display, claiming he had discovered the remains by chance.

The same year Lionel taught his son how to preserve animal bones, Joyce began increasing her daily consumption of Equanil, laxatives and sleeping pills, further increasing her distance from her husband and children.

From his freshman year at Revere High School, Dahmer was seen as an outcast.

By age 14, he had begun drinking beer and hard alcohol in the daylight hours, frequently concealing his liquor inside the jacket he wore to school.

When a classmate asked why he was drinking Scotch in a morning history class, Dahmer shrugged and said the alcohol was "my medicine".

Dahmer was later sentenced to a sixteenth term of life imprisonment for an additional homicide committed in Ohio in 1978.

He was convicted of fifteen of the sixteen homicides he had committed in Wisconsin and was sentenced to fifteen terms of life imprisonment on February 17, 1992.

On November 28, 1994, Dahmer was beaten to death by Christopher Scarver, a fellow inmate at the Columbia Correctional Institution in Portage, Wisconsin.
