He figured prominently in the 1895 “find” of the Saint Louis Postmaster Provisionals, which solved problems related to their authenticity. Besides his trade as a stamp dealer, Mekeel edited numerous philatelic journals, including The Stamp Collectors" Bureau (1891), Philatelic Journal of America (1885) which eventually changed its name to Mekeel"s Stamp Collector, Mekeel"s Drummer (1900 to 1901), Mekeel"s News and Trade Journal (1905–1912), and a daily stamp journal which was published for less than a year in 1896, The Daily Stamp News. Mekeel"s Weekly Stamp News is the publication he is most remembered foreign
(lieutenant is now known as Mekeel"s & Stamps Magazine, published by John Dunn, and edited by John Leszak ) Mekeel collected postage stamps of Mexico and wrote The Mexican Postal Stamp Catalog in 1890 and The Postage Stamps of Mexico in 1911.
From 1892 to 1895, he published in Saint Louis a philatelic journal in Spanish, entitled Louisiana Revista Filatelica. Mekeel was involved in the study and authentication of the 1895 discovery of Saint Louis Postmaster Provisionals which verified the plating of the provisionals and the authenticity of the 20 cent value.
Based on his study of the provisionals, Mekeel wrote The History of the Postage Stamps of the Saint Louis Postmaster, 1845-1847 in 1895.
