A first measurement of the $\mathrm{b}$ quark fragmentation function at theLHC is presented. Charmed meson candidates produced via semi-leptonic$\mathrm{t\overline{t}}$ decays ($\mathrm{t} \to \mathrm{b}\mathrm{W} \to$b-jet $\ell \nu$) are used as a proxy for the parent $\mathrm{B}$ meson.Templates are generated at various values of the fragmentation shape parameter$r_{\mathrm{b}}$, and are fit to the data to measure the value of$r_{\mathrm{b}}$. The final fit result is $r_{\mathrm{b}}=0.855 \pm0.037\;\mathrm{(stat)} \pm 0.031\;\mathrm{(syst)}$. This is the firstmeasurement of the $\mathrm{b}$ quark fragmentation function within a colorrich environment, and is consistent with previous results from $e^+e^-$colliders.
