Source-derived summary

Lotte Hass (6 November 1928 – 14 January 2015) was a pioneering Austrian diver, underwater photographer and model. She was nicknamed The First Lady of Diving. She was the first woman to dive in the Red Sea, the first woman to dive with autonomous diving equipment and the first underwater model. She was also the first person to take “in-water footage” of whale sharks and manta rays. She was married to Hans Hass, the Austrian biologist and fellow diving pioneer.

Personal life

Born Charlotte Hildegard Baierl in Vienna to father Karl Baierl and mother Stefanie, née Kitzmantel, she attended Wenzgasse School. In around 1947, rather than go to university, she applied for and got the job of secretary to biologist and diving pioneer, Hans Hass (1919–2013), at the International Institute of Submarine Research in Vienna.

Hans’ marriage to actress Hannelore Schroth ended in April 1950. He proposed to Lotte in November of the same year in Cairo, while returning to Austria after filming in the Red Sea. Their civil wedding was held on 29 November 1950 in Küsnacht on Lake Zurich.

The account is most persuasive where Lotte, Hass and Austrian can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as austrian underwater diver and model; wife of Hans Hass (1928-2015). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 18, 2026. The linked authority identifier is Q93972. VIAF identifies the subject as 22657301. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1928, 2015, 1947 and 1919.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
