Only last name for natbib citep

Question

I want my citations to be shown as (LastName, year) instead of (LastName Initials, year). I am using the natbib package, with setting 'authoryear'.

Below a minimilistic example:

My .tex file:

\documentclass[]{article}
\usepackage[authoryear]{natbib}

\begin{document}

Document body text with citations \\
\citep{Bertram91} \\
\citep{Bertram06} \\ 

\bibliographystyle{authordate1}
\bibliography{myreferences}

\end{document}

And my .bib file:

@article{Bertram91,
        author = "Bertram C.D., Raymond C.J.",
        title = "Measurements of wave speed...",
        journal = "Med. and Biol. Eng. and Comput.",
        volume = "29",
        year = "1991",
        pages = "493--500",
}

@article{Bertram06,
        author = "Bertram C.D., Tscherry J.",
        title = "The onset of flow-rate...",
        journal = "Journal of Fluids and Structures",
        volume = "22",
        year = "2006",
        pages = "1029--1045",
}

This gives the output:

I do NOT want the initials in the citation.

No need to thank or sign in your question. The nice MWE should make it easy for you to get help. — Ethan Bolker, Dec 23 '13 at 13:47
Your input file seems not exactly to conform to the BibTeX syntax. The name format is Last, First and Last, First, so you need author = "Bertram, C. D. and Raymond, C. J." and author = "Bertram, C. D. and Tscherry, J." (or author = " C. D. Bertram and C. J. Raymond" and author = "C. D. Bertram and J. Tscherry"). — moewe, Dec 23 '13 at 14:03
Wow that did change the citations in a major way :) It is now showing correctly. Thank you very much! — Xomesss, Dec 23 '13 at 14:47
@egreg Blast! Of course, I must have been still a bit drowsy. Sorry about that. I assume How should I type author names in a bib file? is much more appropriate, then. I git too entangled in the initials block, though that needed change as well. — moewe, Sep 06 '15 at 06:52

According to your input (and to BibTeX rules), the paper Bertram91 has just one author, whose family name is “Bertram C.D.” and given name is “ Raymond C.J.”.

An author should be given in the form

Family, Given

(also Given Family can be used, but it's better to stick with a scheme; Given can of course be just the initials).

Authors must be separated by and. So the correct syntax for your paper is

@article{Bertram91,
    author = "Bertram, C.D. and Raymond, C.J.",
    [...]

Would you mind if I changed the initials block as in the question I initially voted this to be a duplicate of? — moewe, Sep 06 '15 at 06:58
