Christiane Nusslein-Volhard quotes:

I think there are profound differences between women and men. In intelligence and creativity, there is no difference, but in what one loves, what one likes, the passions - there are differences.

I am often asked why there is discrimination against women in science. And I have given it some thought. With prejudicial attitudes, you can't really do much. You can point out when people discriminate and ask them not to.

I had a happy childhood, with many stimulations and support from my parents who, in postwar times, when it was difficult to buy things, made children's books and toys for us. We had much freedom and were encouraged by our parents to do interesting things.

In mathematics and science, there is no difference in the intelligence of men and women. The difference in genes between men and women is simply the Y chromosome, which has nothing to do with intelligence.

I immediately loved working with flies. They fascinated me and followed me around in my dreams.

Successful women are not liked. I think the biggest danger for women in science is colleagues who are not as good as you are.

I was born during the war, on October 20, 1942, as the second of five children. My father, Rolf Volhard, was an architect.

At the time I finished high school, I was determined to study biology, deeply convinced to eventually be a researcher.

I remember that already as a child I was often intensely interested in things, obsessed by ideas and projects in many areas, and in these topics I learned much on my own, reading books.

In German science, we have a special problem. We lose talented women at the time they get pregnant. Some of it occurs because they are encouraged - by their husbands, bosses and the government - to take long maternity leaves.

I had a very intense relationship with my father, who was always extremely interested in what we kids were doing. I actually think the secret of many successful women is having a father who encourages them.

People think if you have deciphered the genome of humans that you can change everything. But you cannot change everything, because you do not know what the genes mean, and you have no methods for changing them, and you can't do experiments with humans like you can with animals.

Everyone thinks I must have been an ace in school. But I didn't work hard, I was lazy. I liked to be lazy. I thought laziness stimulated your imagination.

I immediately loved working with flies. They fascinated me, and followed me around in my dreams.

I was raised with this idea of hard work and keeping doors open. To be able to choose what you want to do in the future. That was what we tried to tell our children, too.

I think there is too much attention on mentoring. If people want to be scientists, they will figure out how to do it. They need to figure it out by themselves.

I think women who are pretty certainly have an advantage in any field, in any profession. When a girl is born people still say: Oh, I'm glad that she is pretty. They don't look at whether she is intelligent.

Not everybody is talented for doing research. I think many women prefer to look for an easier job after their dissertations because it is very demanding. You have to be mobile. You have to move to different places for your post-doc training. And if you aren't successful, it isn't a very pleasant job, either.

In systemic searches for embryonic lethal mutants of Drosophila melanogaster we have identified 15 loci which when mutated alter the segmental patterns of the larva. These loci probably represent the majority of such genes in Drosophila. The phenotypes of the mutant embryos indicate that the process of segmentation involves at least three levels of spatial organization: the entire egg as developmental unit, a repeat unit with the length of two segments, and the individual segment.

It is very important for me to be taken seriously for my science and not for my looks or other personal accomplishments.

I was always trying to look modest and natural. I don't like women who come into the lab and you see immediately that it took them two hours to dress in the morning.

The pressure on kids is high to get good grades. In my time, no one cared about it. My father looked at them but he didn't really make much fuss about them.

The three of us have worked on the development of the small and totally harmless fruit fly, Drosophila. This animal has been extremely cooperative in our hands - and has revealed to us some of its innermost secrets and tricks for developing from a single celled egg to a complex living being of great beauty and harmony. ... None of us expected that our work would be so successful or that our findings would ever have relevance to medicine.

The drive to want to know is innate in people. You cannot influence this. I think in contrast it is harmful if you push kids too far in a particular direction.

In my age group I don't know a single woman who is as successful as I am. I am the total exception. You can be very proud of it. But you are also very isolated.

If woman wants to have kids and work a little less she has a big disadvantage compared to a male colleague who has a stay-at-home wife packing his suitcases.

I think women are just as gifted when it comes to science as men are. But I think their wishes and desires are different and this is also shaped by the society in which they live.

I know labs where women refuse to make a coffee for others because they don't want to be seen doing seemingly female things. I think this is stupid. Why not make a coffee, bring a cake? I do it.
