Ulrich Lichtenthaler 

Early in 2012, a group of 20 scientists became aware of deficits in Lichtenthaler's publications. This led the group to take a closer look at 50 other publications authored and co-authored by Lichtenthaler. The group's examination concluded with severely criticizing Lichtenthaler's work on the following points:

• lack of cross-referencing to publications of his own;
• his diverging interpretation of the same data set in different publications;
• severe statistical mistakes.

The controversy resulted in several of Lichtenthaler's articles being removed or retracted from the journals Strategic Organization, Research Policy, Strategic Management Journal,Journal of World Business, Organization Science, Journal of Business Venturingand Journal of Product Innovation Management. As a consequence of this controversy, both WHUand the University of Mannheim have created commissions tasked with investigating the suspected transgression of scientific standards by Lichtenthaler.

Rick Heber

Known for his work as principal investigator of the Milwaukee Project and the subsequent controversies surrounding the project. ... Heber was a member of the faculty of the University of Wisconsin at Madison when he was indicted on charges stemming from the misuse of federal funds allocated to the project. He was subsequently convicted and served time in the federal prison in Bastrop, Texas. Previously a respected scholar in the field of mental retardation, his academic work on the Milwaukee Project has been called into serious question. It is now questionable whether the project ever actually existed as it had been described by Heber.
