The man best known for taking a stand against the oil industry has died of esophageal cancer.
Ludwig, 70, spent nearly 20 years at odds with the oil industry.
He claimed that oil and gas developments were to blame for the poor health of his family and his livestock.
Between 1996 and 1998, there were at least 160 incidents at oil and gas facilities in northwestern Alberta, ranging from nails strewn along lease roads to shootings and bombings.
In April 2000, Ludwig was convicted of charges linked to the bombing of a Suncor well site near his family compound in Trickle Creek, near the community of Hythe.
He was also found guilty of encasing a Norcen Energy well in concrete.
In 1999, he was investigated for the shooting death of a teenager who was joy riding on his property.
His most recent clash with the law came in 2010 where he was arrested and his property searched in connection to six pipeline bombings near Dawson Creek.
Some items were reported seized by police but Ludwig was never formally charged.
A man who wrote about Ludwig in his book ‘Saboteurs' says he possessed an animal energy and spirit.
"He was almost totally fearless but he was a man provoked," says Andrew Nikiforuk. "He spent five years civilly trying to get regulators and government to address what I think is very legitimate concerns about sour gas development and pollution. He didn't go on a warpath until he was ignored and rudely treated by officials."
Ludwig knew he had contracted cancer last year but was seeking alternative medicine to cure it because he felt conventional treatments and surgeries were too invasive.
According to his son Josh, he died at home with his family.
"We will miss him as one who steadfastly and selflessly upheld the hope of the Gospel of Christ, as a loving husband, father and grandfather," the family said in a release.
Ludwig leaves behind his wife, their 11 children, and 23 grandchildren.
