Paul Hagenmuller’s scientific production
• He published 796 papers (Scopus DB) with his 1st paper in 1945
• His work was rapidly recognized (1382 total citations in 1980); by 2015, his work was
cited more than 16276 times

Delayed recognition

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)

Investigating delayed recognition
• Calculation of the “Beauty coefficient”

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 ?
