Memories Timeline

  3. Aunt Mel was the sweetest and I will always remember her calling everyone hon, always being kind and warm. She was loved and will definitely be missed. Love, Megan

  4. The following will appear in a forthcoming issue of the Philatelic Literature Review, which is published by the American Philatelic Society. RMPL is the acronym for the Rocky Mountain Philatelic Library in Denver. The dozens of volunteers at RMPL will miss Mary Ellen.

    “Mary Ellen Markel: A 20 year volunteer at the RMPL, Mary Ellen was a quiet, unobtrusive member of the library who first began her volunteer work under the tutelage of Bill Dunn, continued through Ron Mitchell, Sergio Lugo and recent Presidents of the RMPL. She toiling away at her delight – sorting and arranging stamps of every kind for the enjoyment of RMPL members who purchased those stamps for their collections at remarkably low prices. A medical records secretary for near on four decades, Mary Ellen balanced that work-life with her volunteer participation at her Home Owner’s Association and the RMPL. She rarely participated in RMPL social activities, and until half a decade ago, always visited with nieces in Nebraska over the Christmas and Easter holidays. She always enjoyed reminiscing about her extended family and friends, the formative teen and early adult decades of the 1930’s and 1940’s, and the evolution of western America, and in particular the range-lands of the west. A particular delight as she grew older was her close relationship with Jack Sweigert, her cousin, and world famous Apollo 13 astronaut and his untimely short service as a U.S. Congressmen from Colorado. A gentle, and quiet soul who passed through our ranks as a stamp collector and thoroughly knowledgeable worldwide philatelist will be missed. (Sergio Lugo and Paul Albright.) “
