Source-derived summary

The Thomas Disaster known in German media as Thomas-Katastrophe was an explosion incident involving the North German Lloyd steamer SS Mosel at the Bremerhaven docks on the 11 December 1875. It killed around 81 people and more than 200 were injured. It was the result of a dynamite-based explosive with a timing device that accidentally went off when the explosive package was loaded into the ship. The bombing was part of a plan to commit insurance fraud by the Canadian Alexander Keith Jr. who, at the time went by the name of Thomas or Thomassen. He shot himself shortly after the explosion and died a few days later, confessing to the crime during interrogations by the German police.

Incident

The steamship Mosel belonged to the North German Lloyd company and on December 11, 1875 it was to set off for New York under Captain Leist, the originally assigned captain Hermann Neynaber having taken ill. It had 400 passengers mostly from Germany who had already boarded and it was towed by the tug Simson and was being temporarily docked to load some cargo. A large number of onlookers were assembled including those that had come to bid farewell to the passengers. One of the large packages of cargo to be loaded was armoured in iron and weighed 650 kg (1,430 lb).

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as bomb attack and insurance fraud in Bremerhaven, 1875. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q26269186. Authority coordinates are 53.545, 8.569. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1875.

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.
