Jeanne Collier
former American Olympic diver
Jeanne Ellen Collier (born May 15, 1946), known by her married name as Jeanne Collier Sitzberger after 1966, is a former American springboard diver who swam for the Dick Smith Swim Gym in Phoenix, Arizona. She competed at the 1964 Summer Olympics in Tokyo and won a silver medal in the 3 meter springboard.
Collier was born one of five siblings on May 15, 1946, to Robert Michael and Lucy Collier, in Indianapolis, Indiana. Demonstrating a remarkable early talent and an affinity for the sport, she first took to diving around the age of ten, and by twelve was competing in national competitions. Distinguishing herself nationally in her early career, she attended the 1960 Olympic trials at the age of 14. After a move to Phoenix, she swam for the Dick Smith Swim Gym, and in the summer of 1961, won the 3 meter diving competition at the Jr. National Championships in Denver prior to her High School Sophomore year. At the U.S. Senior National Diving Championships in Philadelphia in 1961, Jeanne took a sixth place in the 3 meter diving event. Among an array of adult competitors, she was the second youngest. Collier was named to the 1962 All America team.
This brief starts where responsible research should: with the source description of “Jeanne Collier” as former American Olympic diver. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as former American Olympic diver. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q6172049. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1946, 1966, 1964 and 1960.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
