This document summarizes a presentation about Paul Hagenmuller's scientific contributions and instances of delayed recognition in his work. It discusses that Hagenmuller published over 796 papers with his earliest in 1945, which were cited over 16,000 times by 2015 despite an initial period of limited recognition. The presentation analyzes seven of Hagenmuller's papers that exhibited characteristics of "sleeping beauties" in science, being largely uncited for 5-10 years before experiencing renewed interest. These papers covered topics including clathrate structures, layered oxides, and electrochemical intercalation/deintercalation, and saw simultaneous increased attention in the late 2000s with industrial applications in sodium-ion

Delayed recognition paper
or Sleeping-beauty in science
• Definitions
• Delayed recognition, (Garfield, 1980), premature or resistant
discoveries (Burel, 2005; Braun, 2010), sleeping beauty (Van Raan
(2004):
• “articles that go unnoticed (“sleeps”) for a long period of time and then,
suddenly, receives a lot of citations by a “prince” (another article).”
• Average-based criteria (Van Raan et al, 2014)
• depth of sleep: at most 1 citation/y (deep sleep) or between 1 & 2
citations/y (less deep sleep)
• length of the sleep: between 5 & 10 years
• awakening intensity: 15 citations/y for 4 years
• Quartile-based criteria (Costas el al., 2010 & 2011)
• Parameter-free index: The Beauty coefficient (Ke et al, PNAS, 2015)
• Others:
• K-value (Teixera et al., 2017),
• Citation-angle (Yea et al., 2017)

Conclusions
• Although Hagenmuller was a recognized scientist, part of his work suffered
from delayed recognition
• Sleeping-beauties are not exceptional in science (1,2 -7,6%)
• But Paul Hagenmuller authored 7 SBs
• With a bundle of 5 SB papers
• Explanations ?
• Lack of immediate relevance of findings to the existing state of
knowledge; newly identified compounds w/o applications
• Curiosity-driven research
• Awakening with industrial applications
• Linguistic limitations
• SB#2, 4 & 6 were published in French
• Conclusion
• Relevance of short term citations indicators in evaluating research
• Further works
• Who are the Prince ?
• Occurrence of other SBs in (Solid-state) chemistry ?
