From ANIMAL PEOPLE, October 1998:

Helen Jones, 73, died of carbon monoxide
poisoning during a morning fire on August 14 at her
home in Abington Township, Pennsylvania. Arriving
for work, her hospice care nurse Debbie Moore,
Moore’s husband Raymond, and a police officer they
summoned saw the fire and pulled Jones from her
burning bedroom, but too late to save her.
Cofounding the Humane Society of the U.S.
in 1954, to more vigorously oppose vivisection and
hunting than the existing national animal advocacy
groups, Jones became disenchanted, and left to form
the National Catholic Society for Animal Welfare in
January 1959. On July 10, 1966, Jones led the first
protest for animals at the White House, opposing the
then-pending Laboratory Animal Protection Act––
against the views of all other major animal protection
groups––because she believed it did more to legitimize
vivisection than to save animals. Jones moved
NCSAW from Washington D.C. to New York City in
1974, and retitled it the International Society for
Animal Rights, as the first national advocacy group to
embrace an explicitly “animal rights” philosophy.

From ANIMAL PEOPLE, October 1998:

Henry Spira, 71, died in his sleep
on September 12 from esophageal cancer,
after an uncomplaining three-year battle.
Encouraging Peter Singer to expand a 1973
essay on why animals should enjoy rights into
the book Animal Liberation, while taking a
night course from Singer, Spira virtually created
the animal rights movement by leading
his classmates in converting the ideas they had
discussed into political action.
Along the way, Spira learned that
more than 100 years of antivivisectionism
hadn’t ever stopped a cruel experiment. He
changed that with the 1976-1977 campaign
that persuaded the American Museum of
Natural history to end 18 years of sex experiments
on maimed and disfigured cats.
