• You'll have to be more specific. MathSciNet search on "algebraic" and "structures" anywhere, restricted to 1900-2000, returns 106 pages of results. – Conifold Jan 10 at 23:50
• Are you asking about specific examples of algebraic structures, such as the monster group predicted in the 1970s and others identified as part of the classification programme, or are you asking only about abstract algebraic structures not carried forward from the 19th century. – Nick R Jan 11 at 0:11
• Missing the cut by three years (1897) would be Hensel's introduction of the p-adic completions of $\mathbb Q$. – Nick R Jan 11 at 0:16
• I think that a good source is : Leo Corry, Modern Algebra and the Rise of Mathematical Structures (2nd ed, 2004). – Mauro ALLEGRANZA Jan 11 at 9:08
• Do you mean: The first paper to state axioms for "group". The first paper to state axioms for "groupoid". The first paper to state axioms for "boolean algebra". And so on? – Gerald Edgar Jan 11 at 11:54
