Notable deaths of 2017 -- Hugh Hefner, Edith Windsor, Charles Manson and others we lost this year

UPDATED: Famous crime novelist Sue Grafton and civil rights activist Erica Garner, daughter of Eric Garner, each passed away in late December.

They were among the last notable figures to pass away in 2017, a year that was marked by the loss of beloved celebrities, athletes that transcended generations and innocent people who were gunned down in two of the most horrific mass shootings in modern United States history.

One of the first notable losses of the year came in January with the passing of legendary actress Mary Tyler Moore. The television icon who starred in "The Mary Tyler Moore Show" and "The Dick Van Dyke Show" was one of the most beloved actresses in modern history. She was diagnosed with Type 1 diabetes in her early thirties and went on to become an advocate for the Juvenile Diabetes Research Foundation.

Female pioneers who helped shape our history were lost this year, including Clare Hollingworth, a veteran war correspondent widely known for breaking the news that WWII had started, died at the age of 105 in January.

Norma McCorvey was also among the year's deaths. She was the person behind the anonymous "Jane Roe" in the landmark Roe v. Wade case, which ultimately led to the legalization of abortion in the United States in the 1970s. McCorvey eventually split from pro-choice activists and joined the pro-life movement to advocate against abortion, despite her role in its legalization.

The year also saw the death of LGBT rights pioneer Edith "Edie" Windsor, who fought to overturn the Defense of Marriage Act, and was the lead plaintiff in the landmark case that led to the legalization of same-sex marriage. Windsor died at the age of 88 in September.

The year also brought the passing of a man who built an empire with women at his side and spread throughout the pages of his magazine, as Playboy founder Hugh Hefner died in September. He became a household name and made millions as an advocate for sexual freedom and the lifestyle he embodied for more than six decades.

Several controversial figures also died this year. Infamous cult leader Charles Manson died of natural causes in a California hospital in November. Former NFL star Aaron Hernandez reportedly committed suicide in his jail cell in April. The "blind sheik" convicted in the 1993 World Trade Center bombing died in prison in February and former Auschwitz guard Reinhold Hanning died in May.

The sudden loss of former MLB star Roy Halladay shocked the sports world in November. The two-time Cy Young award winner, known by many as "Doc," was killed when his plane crashed in the Gulf of Mexico. The oldest living major league baseball player, Bobby Doerr, also died in November. The Boston Red Sox legend was 99 years old.

The year also saw the loss of many who were never famous until their tragic deaths -- including a total of 84 people who were killed in two separate mass shootings in America in 2017. Stephen Paddock gunned down 58 people at a music festival in Las Vegas in October. The victims ranged in age from 20 to 67. A month later, Devin Patrick Kelley killed 26 when he opened fire on a Texas church. One family lost nine family members in the tragedy.

More than 30 U.S. troops were killed in action overseas in 2017, including four Army Special Forces soldiers. Sgt. Jeremiah Johnson, Sgt. Bryan Black, Sgt. Dustin Wright and Sgt. La David Johnson were killed in an ambush in Niger in October. There were also more than 120 police officers killed in the line of duty.

The year also saw the loss of some who one might consider "everyday heroes" like David Henneberry, the man who found Boston Marathon bombing suspect Dzhokhar Tsarnaev hiding in his boat, who died in September. Anthony Senerchia, the activist who helped inspire the "Ice Bucket Challenge" phenomenon in 2014, died after a long battle with Lou Gehrig’s disease in November.
